Porn star Brent Corrigan said last week that he declined to participate in a James Franco-produced movie about the murder of adult film producer Bryan Kocis.

King Cobra is based on the 2007 murder of Kocis, head of Cobra Video, the studio which had an exclusive contract with Corrigan, real name Sean Paul Lockhart.

“The internet has been a buzz regarding some recent news that a movie is being filmed right now in New York State chronicling the Bryan Kocis murder and the early days of my adult career,” Corrigan wrote in a Facebook post.

“I was originally approached to be a part of the film as a consultant and the cast. I was asked to play a small part in the film and declined the role.”

Corrigan said that he's writing a book about his experience, which he suggested would be published in the coming year.

“I look forward to finally telling my story, beginning, middle and end, with an earnest stroke,” he added.

Porn star Harlow Raymond Cuadra and Joseph Manuel Kerekes, who produced their own adult films, wanted Kocis to let Corrigan star in one of their videos opposite Cuadra, but Kocis would not let his star model out of his contract. Cuadra and Kerekes were convicted of Kocis' murder.

Garrett Clayton is set to play Corrigan in King Cobra, while Christian Slater will play Kocis. Molly Ringwald will also appear in the film.
