Marlon Brando may be the most famous Hollywood exponent of method acting, even if the double Oscar-winning star of On the Waterfront and The Godfather always refused to accept the tag. But even Brando’s efforts to prepare for a part – which once involved him living alongside wounded soldiers in a veteran’s hospital for a full month to play an injured second world war lieutenant in his 1950 film debut, The Men – pale into comparison with those of some of his spiritual successors.

In the wake of Australian actor Jai Courtney’s revelation that he swallowed magic mushrooms and stubbed cigarettes out on his arms to play the unhinged antihero Boomerang in the forthcoming comic-book epic Suicide Squad, here are some of the most inventive and extreme examples of Hollywood A-listers taking their art a little too seriously.

Leonardo DiCaprio’s bison liver-crunching in The Revenant

In ‘living hell’ … DiCaprio in The Revenant.

Alejandro González Iñárritu’s visually spectacular frontiersman epic was shot in brutal conditions in remote, frozen corners of Argentina, the US and Canada. But at least the film’s crew, who complained of being subjected to a “living hell” of long hours, extensive delays and temperatures dropping to -25C (-13F), had DiCaprio along for the ride. Perhaps with one eye on awards season glory, the Titanic star, who is vegetarian, chowed down on raw bison liver, climbed inside a horse’s carcass and waded through a frozen river. He did not, however, fight it out with a real bear: the movie’s central animal attack was Iñárritu’s only concession to CGI, and was shot with a rather foolish-looking bloke in a mo-cap bear suit.

Effort: 6/10

Was it worth it? Indubitably. DiCaprio won his first best actor Oscar, while Iñárritu took home best director and Emmanuel Lubezki won best cinematography for his searing camera work.

Shia LaBeouf’s tooth-pulling antics on Fury

To prepare for his role as a Bible-toting tank gunner in David Ayer’s claustrophobic second world war drama, the one-time teen idol made himself hugely popular with fellow cast members by refusing to wash for four months, resulting in his banishment to a bed and breakfast in a remote village far from the production’s regular hotel. And just in case anyone imagined the Transformers star might not be fully immersed in the horrors of life on the battlefront, LaBeouf also pulled out a tooth and cut his face.

Effort: 9/10

Was it worth it? Fury was well received and LaBeouf is no longer best known for his role in Michael Bay’s moronic sci-fi saga. But Shia didn’t receive any awards-season glory.

Adrien Brody’s hungry holiday for The Pianist

Brody lost 13.6kg (2st 2lb) to play real-life concert pianist and Holocaust survivor Władysław Szpilman in Roman Polanski’s harrowing war drama. He also practised piano four hours a day until he was able to play passages by Chopin – all this after quitting his US apartment and selling his car to get to the German shoot. “There is an emptiness that comes with really starving that I hadn’t experienced,” Brody told the BBC. “I couldn’t have acted that without knowing it. I’ve experienced loss, I’ve experienced sadness in my life, but I didn’t know the desperation that comes with hunger.”

Effort: 7/10

Was it worth it? Absolutely. Brody became the youngest person to win an Oscar for best actor and Polanski was the surprise winner of the best director gong.

More tooth pulling from Nicolas Cage in Birdy

Cage’s early effort saw the actor engage in a spot of amateur dentistry to play a Vietnam war veteran with horrible facial injuries. “They were baby teeth,” the future Oscar winner told the Telegraph’s Anne Billson in 1985. “So I took advantage of it and had them out. I thought it would add an interesting dimension to the role.” Cage also took to wearing a bandage around his head during filming, which when removed gave him a sinister, sickly appearance due to the resulting acne and ingrowing hairs. “The reactions on the street were brutal,” Cage revealed. “Men and women laughing, kids staring.”

Effort: 8/10

Was it worth it? Alan Parker’s tale of blue-collar Philadelphian vets won the grand jury prize at Cannes, and if nothing else, helped established Cage’s reputation for risk-taking and theatricality.

Hilary Swank lives as a trans man for Boys Don’t Cry

Swank, who had been completely unknown in Hollywood, lost weight to accentuate her bone structure and lived as a man for a month to play murdered transgender man Brandon Teena. Her transformation was so convincing that neighbours at the actor’s home thought her brother was visiting. At the behest of director Kimberly Peirce, Swank also wore socks in her underwear and bound her breasts, as Teena had done.

Effort grade: 8/10

Was it worth it? Swank was catapulted to overnight fame, winning the first of two best actress Oscars.

And tonight, Matthew, Val Kilmer is Jim Morrison in the Doors

To get in the groove for the role of the Riders on the Storm crooner, Kilmer learned 50 songs from the band’s back catalogue and interrogated former Doors producer Paul Rothschild for months, learning specific intonations to help him perfectly channel the spirit of the 60s rocker. “Val knows Jim Morrison better than Jim ever knew himself,” Rothschild told the Washington Post in 1991. “To the extent that the Doors had difficulty telling whether it was Val singing or Jim singing. Early on, I’d bring them into a recording studio and I randomly switched Val and Jim and they guessed wrong 80% of the time.”

Effort: 6/10

Was it worth it? Kilmer won praise for his performance, but critics thought Oliver Stone’s direction was self-important and the Doors themselves said they failed to recognise their former bandmate.

Robert De Niro driving a real cab for Taxi Driver

To prepare for his role as paranoiac ex-marine Travis Bickle in Martin Scorsese’s 1976 classic, De Niro lost more than two stone and drove a real New York taxi during breaks from shooting Bernardo Bertolucci’s 1900 in Rome. Upon being recognised by a passenger, he is said to have replied: “Well, that’s acting. One year the Oscar, the next you’re driving a cab!”

Effort: 6/10

Was it worth it? Taxi Driver won the Palme d’Or at Cannes in 1976 and picked up four Oscar nominations, including best actor for its star, who appeared in almost every scene. Scorsese’s fractured, dreamlike neo-noir is now considered one of the film-maker’s best movies.

Daniel Day-Lewis total-immersion performing in My Left Foot

Day-Lewis is famous for overdoing it a bit, and once lived for days in the wilds of Alabama to prepare for his role as a frontiersman living as a Native American warrior in Last of the Mohicans. While shooting Jim Sheridan’s biography of the paralysed Irish poet Christy Brown, who was born with cerebral palsy, the English actor refused to come out of character even while the cameras were not rolling. In practice, this meant Day-Lewis spent the entire shoot in a wheelchair, occasionally having to be carried to different parts of the set, and even had to be spoon-fed at mealtimes.

Effort: 8/10

Was it worth it? Day-Lewis won the Oscar, but no doubt really annoyed the kitchen staff.
