In the conversation about violence in movies, when people point out how violent many cartoons have always been, they are very often referring to Tom & Jerry, who started finding creative ways to kill, maim and disfigure each other nearly 70 years ago in 1940. Somehow, however, I think we can expect their next big project to be toned down just a bit, as Variety reports that Warner Bros is eyeing Tom & Jerry as a way to "create their own Alvin & the Chipmunks-like family franchise." As CGI characters in a live-action world, Tom & Jerry will star in an origin story of how they first meet before getting lost in Chicago, and the definitive cat and mouse rivals have to team up to find their way home. A new screenwriter, Eric Gravning, has been hired to work on Tom & Jerry, which is being produced by Warner Bros' Dan Lin (Terminator Salvation: The Future Begins, Sherlock Holmes), and will probably be destroying one of your cherished childhood memories by 2011 or so.
