A controversial new film about 9/11 is raising eyebrows, not only for its content, but also for the people involved in the project: Rosie O'Donnell and Charlie Sheen. The sitcom actor and talk show hostess have both become spokespeople for the 9/11 conspiracy movement. The video Loose Change" ... has been floating around the Internet for years, but now Sheen is in talks with Magnolia Pictures to narrate a new version of the video and redistribute it. Sheen believes the government may have been behind the attacks. O'Donnell has been using her Web site to reprint excerpts from the 9/11 conspiracy site, Whatreallyhappened.com. Magnolia Films founder Mark Cuban, who also owns the Dallas Mavericks, said they're also looking for a film telling the other side of the story, saying "we like controversial subjects."
