His movies grossed $1.3 billion last year. Now the underestimated A-lister attempts to own summer again as he reveals how he rebooted his career and the bouts of depression that pushed him: "Eventually you are all cried out."

This story first appeared in the June 27 issue of The Hollywood Reporter magazine.

It's mid-June in Australia, and I'm working out in a Gold Coast gym with the artist formerly known as The Rock.

Well, working out is something of an exaggeration for this exercise in masochism, as Dwayne Johnson guides me through three different triceps maneuvers, then tackles the biceps, making each merciless hammer curl look as easy as lifting a chicken wing.

"Lower it all the way," says Johnson, 42, slyly amused by my trepidation, "then you'll get that extra part of the muscle working. Like this ..."

I watch his biceps bulge like a balloon. The man isn't just huge, he's gargantuan — a 6-foot-5, 252-pound mountain of muscle, his arms hardened and honed, his chest as big as a bull's. His upper body is covered with tattoos: a flower on his shoulder blossoms into a full-blown male figure on his chest, with a healthy smattering of shark's teeth thrown in for protection. "The warrior is over my heart, which is the overall sentiment," he says. In case you didn't guess.

This is Hollywood's reigning action hero, an ambitious wrestler turned actor, as smart as he is supple, as driven as he is dynamic. Combining several traits of the '90s action stars — the wit of Willis, the strength of Schwarzenegger, the heart of Stallone — he's become the go-to guy for studios anxious to reboot their franchises.

But his aspirations are far greater than being a repo man for the majors. "What do I want?" he says. "I want the world."

Twelve years after Johnson's inauspicious big-screen debut in 2001's The Mummy Returns — and after a decade of "singles and doubles," as he puts it — he is poised to go from a dependable player to MVP, if two mammoth upcoming releases deliver.

First is MGM/Paramount's sword-and-sandals epic Hercules, due out July 25. Then there's the 2015 Warner Bros. earthquake disaster flick San Andreas, which Johnson is shooting here in Australia at a salary of about $12 million — the type of number that makes even other A-listers blink.

All this comes after Johnson reached a turning point in 2011, when, dissatisfied with everything he was making (Tooth Fairy, anyone?), he switched agents (from CAA to WME) and publicists, convinced he could do better. "It was incredibly difficult because you develop a friendship over the years," he says. "But it just dawned on me: Change has to happen."

Since then, his star has soared. He helped propel G.I. Joe: Retaliation to a worldwide box-office take of $376 million ($74 million more than its predecessor) and boosted Journey 2: The Mysterious Island to a worldwide gross of $335 million (nearly $100 million more than Journey to the Center of the Earth). More impressive, after he joined the Fast & Furious ensemble in 2011, its earnings doubled, with Fast Five making $626 million compared with its predecessor's $363 million. Fast & Furious 6 went on to generate a whopping $789 million, and Fast & Furious 7 is set to open in April.

His five releases in 2013 together reaped $1.3 billion — more than any other star's box office last year — making him, at least as far as his Hercules and San Andreas producer Beau Flynn is concerned, "the biggest star around."

Johnson has the ease and confidence to go with it. He projects a comfort level with success that makes you think things always have been this way and always will be.

Which makes it all the more surprising to learn this is the same guy who endured massive upheaval as a child; got into frequent trouble with the law as a teenager; was kicked out of his home at 14; and faced the end of everything he had dreamed about when he was dumped as a professional football player, sending him into a crippling tailspin of despair.

"I didn't want to do a thing," he recalls. "I didn't want to go anywhere. I was crying constantly. Eventually you reach a point where you are all cried out."

Sitting in the cavernous living room of his rented house a few hours after our workout, wearing a hoodie that has his hero Muhammad Ali's name scrawled across it, Johnson shows no trace of his turbulent past.

He chats happily about his nonworking life — about the books he's reading (Malcolm Gladwell's Outliers and Hillary Clinton's Hard Choices), the TV shows he watches (HBO's Real Sports, Oprah's Lifeclass and Locked Up Abroad) and his love of fishing. "I'm a passionate, hardcore fisherman," he says. "Biggest fish I caught? A 200-pound tarpon."

He also speaks openly of his live-in girlfriend, writer-musician Lauren Hashian, 29 ("She embraced and loved me at my very worst and lifted me up to be my very best"), and of his ex-wife and longtime manager, Dany Garcia, 45 (whom he met as a student and divorced in 2008). The mother of his 12-year-old daughter, Simone, Garcia oversees every aspect of his business empire, and her family has become his — her brother, Hiram, is Johnson's producing partner; her husband, Dave Rienzi, is his conditioning coach.

He describes his current life with a sophistication not always apparent onscreen, laughing readily and infectiously. But his past is never too far from his mind. "I remember it as if it were yesterday," he says.

Johnson was 14 when he came home and found an eviction notice pinned to the door. He was living in Hawaii with his mother, Ata, while his father, Rocky, a professional wrestler, was scraping a living going from one wrestling circuit to another. (An only child, Johnson is the son of a Samoan mom and an African-American dad.)

"We were living in an efficiency that cost $120 a week," he recalls. "We come home, and there's a padlock on the door and an eviction notice. My mom starts bawling. She just started crying and breaking down. 'Where are we going to live? What are we going to do?' "

Johnson was devastated. He almost chokes up describing that time and his sense of hopelessness. Just a week earlier, he'd witnessed his mother in tears when her car was repossessed; he had added to her burden by getting into fights and joining a theft ring that preyed on the most affluent stores in Waikiki, which often landed him in the hands of the police.

He was angry at his father for being absent and for forcing him to move some 13 times during his childhood, staying in some places for just a few months at a time. Once, in Nashville, after he had sprouted to his full height, his fellow students were convinced he was an undercover cop and refused to talk to him. "It was like I had an APB out on me," he says.

As his mother scrambled for the work that would land them a new home, he resolved never to go through this again.

"That was the tipping point," he says. "It was about, 'What can I control with these two hands?' The only thing I could do was train and build my body. The successful men I knew were men who built their bodies."

And that's what he did — pounded his muscles with weights, pushing himself until he went from being a gangly, pimpled youth to a leviathan who could legitimately envision a career in the NFL.

At 18, he won a full football scholarship to the University of Miami and was ecstatic when he was the only freshman chosen to play, a rarity in college football. He was in love with the game and even dabbled in steroids, thinking that might help, though only for a while, as he didn't see the desired effect. "I tried them when I was 18, me and my football buddies. Nothing happened," he says.

Then, in his freshman year, he sustained the first of several serious injuries: "My shoulder popped out of its socket and was just hanging there." It sent him plummeting into his first of three depressions. "I didn't know what it was," he says. "I didn't know why I didn't want to do anything. I had never experienced anything like that."

He dropped out of school without even taking his midterms and went to stay with his parents in Tampa. For weeks, he remained there, his shoulder in a sling, lethargic and unable to break out of his despair, until his coach called.

"He says, 'Get your ass in a car and come back right now,' " remembers Johnson. "He was so embarrassed and pissed. It's one thing when you go through an injury and depression. It's another when you walk away and say, 'F— it.' "

He did what he was told and restored his standing at the school, still clinging to the dream of playing in the NFL. But more injuries affected his game, and when the draft came, he wasn't picked.

In 1995, he was signed by the Canadian Football League's Calgary Stampeders at a yearly salary of $35,000, nothing like the six figures he had imagined that would have allowed him to make down payments on a home for his mom. Then things got worse: Within months, he was relegated to the practice team, which paid a mere $250 a week.

He was nearly broke, forced to share a two-bedroom apartment with three other players, eating ramen noodles and spaghetti and sleeping on a filthy mattress he had found ditched outside a pay-by-the-hour sex motel. Finally, his coach told him he was being cut. "You hear the words you never want to hear as a player: 'Coach wants to see you. Bring your playbook,' " says Johnson. "There was no injury. It's just, 'That's it. You're not good enough.' That was very sobering."

Experiencing a second depression even worse than the first, he returned to Miami, where the stress led him to split with Garcia. (They would reconcile soon after.) "The dreams I had, they're dashed," he explains. "There is no more football. My relationship was crushed. That was my absolute worst time."

With no car, he called his father asking for a ride, and as they took the four-hour drive from Miami to Tampa, Johnson says: "I looked in my pocket, and I had seven bucks. Wow. Seven bucks to my name."

Abandoning football, he followed his father and grandfather into wrestling, taking the moniker "Rocky Maivia" from his dad's first name and his granddad's last. His father reluctantly agreed to train him, afraid Dwayne was embarking on the same hardscrabble life that had cost him so much pain.

After a few false starts — when fans rejected Johnson's nice-guy image as fake and booed him with the chant, "Rocky sucks!" — he reinvented himself as a bad guy. "There are two terms in wrestling," says Johnson. "Baby face is your hero, heel is your villain. I had no choice but to go heel."

Rocky became The Rock.

He went on to become one of the most successful wrestlers in history, with 17 championship reigns. "I loved it," he says. "I loved the showmanship, and I loved the theatricality. It was so entertaining and over-the-top, and I was always mesmerized by these guys."

The Rock made millions for himself and the WWE, working closely with its chairman, Vince McMahon, to whom he still turns for counsel. He became one of the few modern wrestlers to cross over into mainstream pop culture because, he says, he dared to add a dash of comedy to his bad-guy turn. WWE capitalized on that with massive merchandising (Garcia says together they still are creating six or seven new products a month) and even animated shows like Slam City that feature The Rock as a character.

Five years after Johnson started wrestling, a 2000 hosting stint on Saturday Night Live led to The Mummy Returns, which was followed by more than a dozen films including 2005's Be Cool, 2007's The Game Plan and 2008's Get Smart. Still, the star knew something was missing.

"I was told that I had to conform to a standard in Hollywood that would beget me more work, better roles," he explains. "Which meant I had to stop going to the gym, which meant I couldn't be as big, which meant you had to distance yourself from wrestling. You essentially had to deconstruct yourself."

For a while, he says, he bought into that, in part because he did not have the high-level industry contacts he could turn to for advice. "Then that started to not feel good to me. It reached a point of, 'I'm not feeling authentic.' "

"After [2010's] Tooth Fairy," says Garcia, "we recognized that Dwayne was moving away from his core of who he was."

First they changed publicists. But it was only after a long telephone conversation with Garcia and business manager Howard Altman in 2011 that Johnson realized he had to go further.

The real turnaround came after CAA put together Johnson's Fast Five deal, when he debated returning to the ring for the first time in years, a move his representatives at CAA strongly cautioned against. (He would do so in April 2011 for WrestleMania XXVII.) That was when he bolted.

On McMahon's advice, Johnson spoke to WME's Ari Emanuel, who flew to Johnson's Florida home the next day and invited him and Garcia to a meeting in L.A. with about 150 WME staff, including the man who would become Johnson's key rep, Brad Slater. Johnson was stunned by their enthusiasm and hunger, a hunger he shared.

"I felt there were bigger and better opportunities," he says. "I also felt there was franchise potential, hopefully multiple franchises in every genre — whether drama or comedy or action-comedy. I thought, 'I want people around me who see this, too. And if we fail, that's OK. We are going to fail swinging for the fences.' "

Hercules is part of that swing.

Johnson had contemplated telling the Greek demigod's story ever since seeing the 1958 version of his story with Steve Reeves. He was developing his own film on the subject when he got a call about starring in an MGM movie.

Soon, he signed on with Brett Ratner as director, and the pair prepared for a grueling four-month shoot in Budapest, Hungary. The challenge wasn't easy; unlike his supporting role in the Fast & Furious films, this would mean being in peak physical condition, day in and day out — showmanship level, beyond even his tip-top shape for Pain & Gain.

"You think automatically because he's a body builder, he can do that stuff," says Ratner — in other words, bulk up and stay there for months. "But he had to get up at 2 or 3 in the morning, work out, eat 10 times a day. He had to drink tremendous fluids to keep hydrated. I was always worried about burning him out because it's hard to maintain that level of energy. The crazy part is, three weeks before we started shooting, he whips his groin muscle and gets a hernia."

Johnson had suffered a bad injury in his 2013 return to the ring, when he fell and tore both his rectus tendon and adductor muscle while fighting former nemesis John Cena. After seeing a doctor, he opted against surgery. Two days later, by sheer coincidence, something else went wrong.

"I came in for a checkup and pulled my pants down, and the doctor goes, 'Oh! That's a hernia,' " says Johnson. "Your abdominal wall gets weak and your organs push through. The doctor said, 'You need to lie down,' and slowly starts to push my intestines back in my stomach. He said, 'I would really recommend surgery.' "

That was two weeks before the start of production, and this time Johnson had no choice but to say yes, though the shoot now had to be delayed a month at a cost of $2 million. He was lucky: Other than the delay in shooting, production went well. But soon after his return to Florida, he got devastating news: His Fast & Furious friend Paul Walker had died in a car crash.

"I was driving with Lauren when she immediately turned very quiet and was looking at me, studying, wondering if I knew," he recalls of that November day. "I pulled over and looked at my messages and had a moment where I just caught my breath. We said a prayer right then to give his daughter strength — because we had talked about our daughters. That's what we would talk about. Both of us were divorced, and we talked about the power of being a dad and the strong connection of a dad and his girl. Then once we got home, we started bawling."

The following day, Johnson spoke to NBCUniversal vice chairman Ron Meyer, and the studio began the long process of figuring out what to do. "I had one day of shooting left, and we still have one day left, which we'll shoot in a month or two," says Johnson. As for Walker, he thinks about him a lot. "He was a beautiful man, and in that crazy world, that's really something."

When not filming, Johnson gets up at 4 a.m., does around 30 minutes of cardio, then grabs breakfast (his first of six daily meals) before hitting the weights. Working from his base in Fort Lauderdale, he oversees a fledgling production company, the appropriately named 7 Bucks Entertainment, with a five-man staff there and other employees in Los Angeles and London, pushing into film and TV.

He has a new HBO series, Ballers, a sports-related Entourage in which he will appear as a sports agent, that starts shooting in the fall; and Wake Up Call, a reworked version of his canceled TNT reality-competition series The Hero, where he will help people turn their lives around.

He also is preparing a second autobiography, following his 2000 best-seller The Rock Says. The new, untitled volume is out in the fall, and in addition to his film career, it may go into his 2008 divorce, which plunged him into a third depression — though he doesn't go into details of his breakup. "Once I manned up and became accountable for the mess I was in, that's when it all hit me," he says. "What kind of dad does this make me? What kind of man will I now become? Failing at marriage and as a husband was a heavy thing, and divorce had that special way of knocking me on my ass."

He has not ruled out a return to the ring, though he says its scale — both as an event and a payday — would have to equal or exceed his 2013 fight, and he continues to work with WWE, though film is his real focus.

"He appeals to all ethnicities," says Flynn. "He's very modern. His base is young and his base is old. He also shares himself with his fans through social media — he's got almost 50 million followers — and it's him, not someone else doing it."

Now Johnson is turning to the foreign markets he knows are pivotal to a contemporary star's success.

"In 2014, 70 percent of the punching power of a movie star is outside North America," says New Line Cinema president and COO Toby Emmerich, who is overseeing San Andreas. "When he did a publicity tour in Asia for Journey 2, the reaction he got from fans and the media [was] a needle-mover. Like Will Smith and Tom Cruise, he's building an international audience with good movies and boots on the ground. That's the recipe for a global movie star."

Which is precisely what Johnson wants. He knows he has been given a chance, and he plans to seize it. "I grew up where, when a door closed, a window didn't open," he says. "The only thing I had was cracks. I'd do everything to get through those cracks — scratch, claw, bite, push, bleed. Now the opportunity is here. The door is wide open and it's as big as a garage."
