Moviehole reports a rumor that McG and Warner Brothers have revamped the ending of Terminator Salvation to change it completely from the ending leaked last year on several Web sites, including C.H.U.D. and Ain't It Cool News. (Big spoilers ahead!)

According to those rumors, the big reveal in the film is that Marcus Wright (Sam Worthington) has the endoskeleton of a cyborg in him, and that by the end of the film, John Connor (Christian Bale) is dead and Marcus assumes leadership of the human rebellion, impersonating him by putting on his skin.

For his part, McG denied the rumored ending reports, posting on his blog last June: "By the way, there are only three people who know the ending."

Well, Moviehole is now saying that the ending has changed as a result of the leaked spoilers, citing an anonymous Warner source "who confirmed he'd seen the film, and that there's been big changes to the film over the past few months."

According to the site, "The third act of the film has been completely changed 'because of the Internet leak. The ending doesn't resemble the previous one in any shape or form.' ... The new ending has tested quite well; it's gotten a much better reaction than the 'big reveal' in the script did."

The site said the new ending is "a complete [180] from the original film. Works better. Probably not as hard to swallow. Real good, though."

Meanwhile, the movie's international Web site has been updated with several new images from the movie, which opens May 21 in the United States.
