Much has been made about the unfinished version of 20th Century Fox's upcoming film X-Men Origins: Wolverine that was leaked onto the Internet this week, and the studio head is now speaking out on the matter. Entertainment Weekly spoke with 20th Century Fox chairman Tom Rothman who had plenty to say about the leaked film.

"The version that went out is unfinished. It's about 10 minutes shorter, doesn't have key scenes, it wasn't edited, and none of the effects shots were in any remotely final form," Rothman said. "It's a complete misrepresentation of the film and is deeply unfair to the people who have worked on it for years."

Rothman also said that he feels confident that they'll be able to determine the perpetrators of this leak very soon. Reports surfaces that Australian special effects house Rising Sun was a suspect, due to a watermark that appeared in some scenes, but they have denied the leak, saying they were never in possession of a complete print of the film. Whoever the perpetrator may be, Rothman also said this leak will certainly change the way the studio deals with post-production houses.

"We, like everybody, thought our system was secure," Rothman says. "Just like I'm sure there are lots of banks that get robbed that thought their vault was safe. We thought the post-production pipeline was secure at every juncture. But, obviously, it's self-evident that it wasn't. I have a high level of confidence we'll find out where the lapse in security was and we'll bring the perpetrators to justice."
