harrypotterdh1.jpg Whoops! The first 36-minutes of Harry Potter and the Deathly Hallows: Part 1 leaked online early today, according to TorrentFreak.

The source of the leak has not been identified at this time, but Warner Bros. says it is not taking the matter lightly. "This constitutes a serious breach of copyright violation and theft of Warner Bros. property," the studio tells THR in a statement. "We are working actively to restrict and/or remove copies that may be available. Also, we are vigorously investigating this matter and will prosecute those involved to the full extent of the law."

Last year Harry Potter and the Half-Blood Prince was one of the most-pirated movies with more than 8 million illegal downloads, but the film also grossed $934 million worldwide.
