KEVIN Spacey’s brother reveals how the Hollywood actor used his fame and fortune to mask his true “twisted” nature.

Randy Fowler says the House of Cards star turned to acting and changed his name to hide a “dark side” after a childhood plagued by abuse and denials about his sexuality.

In an exclusive interview, Fowler, 61, admits he has been waiting for the moment allegations about the US screen star would emerge.

Speaking from his home in Idaho, Randy said: “Kevin turned to acting as a little kid. He ditched the name Fowler and created the character of Kevin Spacey to mask a monster. It helped him hide from his demons.

“He struggled with his sexuality, always denying he was gay. On stage he pretended to be somebody else. It gave him power, transformed him.

“We grew up with abuse and neglect in a house of horrors. Our violent dad whipped me with a riding crop ... I’ve never had children in case that evil personality could be passed on.

“Now it sadly seems one of us may carry those twisted genes and that person might be Kevin.

“His fans love the sinister characters he plays, but he’s not acting, that’s really him. He hid behind his acting career to maintain a secret sordid life and in reality he was a monster.

“I’ve long suspected there was a dark side to him. I just hope he gets the help he needs so nobody else is harmed by him.”

The carefully crafted image Spacey, 58, created first cracked in a bizarre incident in 2004 when he claimed he had been mugged while walking his dog in a London park at 4am.

Fowler said: “That was when the wheels of his fake life first started to come off. I thought then it was only a matter of time before the world would know the real Kevin Spacey.

“He’d been trying to lie about who he was for years. In interviews he reinvented his entire childhood.

“He once claimed he’d broken an officer’s leg at military school — but that was me.

“Another time he said he burnt down a building at the back of our house — but that was me too when I burned our chicken coop.

“He has taken pieces of my life and claimed them as his own, trying to portray a man who was a troubled child saved by the theatre.”

Star Trek actor Anthony Rapp has alleged Spacey tried to seduce him when he was just 14.

Spacey then announced he was gay, facing a wave of criticism for the timing.

Now others have come forward with sexual harassment claims, including an actor who was at London’s Old Vic when Spacey was artistic director.

And a British barman says the actor flashed at him outside a hotel then handed over his $8,545 watch to hush him up.

On Thursday, his publicist announced he was going to have treatment. By Friday it was claimed he sexually harassed eight of the House of Cards crew — with one claiming they were assaulted by him.

None of this is a surprise to Fowler. He thinks his brother is following in the footsteps of their father Geoff, a man he calls The Creature. Fowler, whose dad and mum Kathleen are now both dead, said:

“Our father was a Nazi-loving monster who raped and beat me from the age of 14.

“Back then I tried to hide what was happening to me from Kevin.

“I prayed that if I let The Creature hurt me, he’d stay away from Kevin. Now I think I was naive. I once tried to talk to Kevin about it. He said he had no idea dad was like that and wouldn’t discuss it.

“When I heard about these allegations, I prayed history wasn’t repeating itself.” Growing up, the family — including sister Julie Ann, now 66 — were forced to move countless times.

Fowler, who is writing a book about their lives, said: “Dad was a writer who could never hold down a job so they couldn’t afford the rent.

“Kevin went to about ten schools in ten years and became shy and introverted. He never had friends so would hang out with mine.

“Kevin never had a girlfriend either. Of course, I knew he was gay, we all did. He was a mummy’s boy.

“The only people he ever said he loved as a kid were male stars like Frank Sinatra and Christopher Walken. But when I asked him straight out if he was gay when we were smoking a joint one day, Kevin just said, ‘I’m not heterosexual, homosexual or bisexual, just sexual.’

“Kevin should have been honest about who he is. Coming out after being accused of assaulting a 14-year-old is an insult to the entire gay and lesbian community.”

Fowler recalls money was so tight they went hungry and did not even go to the dentist.

He said: “The only holiday we had was to a nudist colony. Kevin was a toddler and surrounded by all these naked adults.

“What kind of parents do that? The Creature even had books of child pornography in his office.”

The brothers always stuck together. Limousine driver and Rod Stewart impersonator Randy, said: “We adored each other. We built forts, rode bikes, escaped outside as much as we could.” The home Randy shares with long-term partner Trish is adorned with photos of the brothers.

But as Kevin became more famous, he froze Fowler out of his life. Spacey started to ignore calls from his brother, who said: “I think I reminded him of ‘Kevin Fowler’ and our childhood. He wanted to get away from that.”

They have only met five times in nearly three decades.

Fowler added: “When mum was dying of a brain tumour in 2002, he didn’t call me until she was so sick she was a vegetable. He robbed me of my last chance to talk to her.”

They last met at her funeral. He said: “Kevin organised it and all his work friends came, which I thought was weird.”

Fowler has repeatedly tried to contact him since without success.

He went on: “I’ve sent birthday and Christmas cards. They are returned in Kevin’s hand writing saying he no longer lives at the address.

“One time when he was in ­London I asked a friend to hand deliver a card to him. Kevin ripped it up without even looking at it.

“I’m speaking out because I want him to know I’m here for him if he needs me.”
