Its been talked about for years, in discussions for ages…"The Simpsons Movie" is finally being set for a July 27, 2007 release. 20th Century Fox snuck copies of a 25-second teaser trailer in front of "Ice Age 2: The Meltdown" this past weekend and also showed it during commercials on last night's "Simpsons" episode. The promo spot advertises the movie for a release next year. USA Today reveals that the movie will most likely be rated PG-13 for language "coarser" than TV. Albert Brooks, Minnie Driver and the real-life Erin Brockovich have also been announced as guest stars. The plot still remains to be a secret but it's been revealed that nearly all the Simpsons characters will make an appearance. Al Jean, Ian Maxtone-Graham, George Meyer, David Mirkin, Mike Reiss, Matt Selman, John wartzwelder, Mike Scully, James Brooks and Jon Vitti are penning the screenplay. David Silverman, series co-producer and animation director, will be directing the feature.
