An anonymous reader writes with this excerpt from geek.com: "In 2009, a copy of X-Men Origins: Wolverine found its way on to Megaupload a month before it was due to appear in movie theaters. The so-called 'workprint' copy was unfinished — so unfinished in fact, anyone viewing this copy saw green screens and wires attached to actors used to help with the more acrobatic movements during action scenes. Hugh Jackman even commented on the leak, describing it as like getting a 'Ferrari without a paint job.' The person who decided to share the movie illegally was tracked down, however. He is a 49-year-old New Yorker by the name of Gilberto Sanchez, and he's just been prosecuted."
The New York Times' 2010 interview with Sanchez
is a good read, too.
