Perry reveals he wanted to make the film about Ralston's five-day battle for life trapped by a boulder in a Utah canyon with former Beverly Hills, 90210 castmate Brian Austin Green.
The actor says, "I tried to acquire the rights to that story and I wanted to do it with Brian Green... I thought he'd be great in that part, but Danny Boyle got it."
But Perry insists he's desperate to do something with Green after recently shooting TV western movie Goodnight For Justice with another old castmate, Jason Priestley.
He tells Access Hollywood, "Brian's a great actor and I've always wanted to find something to do with him."
