The gay porn star who is the subject of a newly released James Franco film has panned the cinematic retelling of his life.

King Cobra, which is based on the early career of Brent Corrigan, aka Sean Paul Lockhart, premiered at the Tribeca Film Festival on Saturday.

Garrett Clayton stars as Corrigan in a cast which also boasts Franco, Alicia Silverstone, Molly Ringwald and Christian Slater.

But the real-life Corrigan hasn't given the film a positive review.

"It's made. And it's not about me. It's Hollywood's attempt at bastardising my early years in porn," Corrigan tweeted.

"These filmmakers didn't care about anyone but their take on it all (and not getting sued)."

Corrigan said he would set the record straight in his upcoming book Incorrigible.

"It doesn't matter what A list celebrity is involved. The screenplay & content didn't jive. I passed it up," Corrigan tweeted.
