The Simpsons Movie is on DVD and in stores December 18th from 20th Century Fox.

The Simpsons had already ruled TV land for many years by the time they finally attempted to conquer the movie world as well. It was never any big secret that a Simpsons movie was in the works: Fox registered the domain name "Simpsonsmovie.com" in 1997, a full nine years before the film was finally greenlighted.

When creator/producer Matt Groening’s creation finally made it to the big screen in 2007, it only turned out to be the biggest hit of the summer, raking in over $100 million gross in box-office receipts in its first week, before heading on to do over $500 million worldwide, proving that the best joke in the movie was actually played on the audience: "Why pay for something when you can see it for free?" asks Homer at the movie’s start.

Naturally, all the trouble starts with him. When he adopts a pig ("Sir Oinks-A-Lot") destined for Krusty’s slaughterhouse, it triggers an environmental catastrophe, forcing the government to seal Springfield into a dome and destroy the city. While the family manages to escape and flee to Alaska, they eventually decide to return and help save the city in more-or-less classic Simpson fashion. As Homer’s joke about the audience shows, Groening and producer Al Jean are keenly aware that their franchise is first and foremost a TV show.
