Even though rumor about Tim Burton making an Addams Family movie were said to be false, Burton's name is apparently still tied to the project according to producer Christopher Meledandri. He said that, as of now, the movie will be stop motion and not computer animated, and in 3-D.
When talking to Comingsoon he said: "It's all very, very early, but we are developing with [Tim Burton directing] in mind. We're just now at the story phase. Stuff has been written as though we are doing it in black and white, but that's not correct. It's not incorrect, but it's not correct. We haven't gotten to that point." So if Tim Burton gets confirmed as the director we'll of course let you know, but as of now it looks like he could or could not.
