A low-quality version of the new Alvin and the Chipmunks poster is now online. In the CG/live-action family comedy, Jason Lee (“My Name Is Earl“) plays David Seville. The film is based on the 1950s cartoon series about chipmunks Alvin, Simon and Theodore, who lay waste to Seville’s surroundings and sing in three-part harmony. 20th Century Fox will release the Tim Hill-directed pic on December 14.They actually look pretty cool in this poster, although Simon seems a bit shorter than he ought to be. Oh and it should probably say “They’re back and smaller than ever,” because this is the first time that they’re actually chipmunk-sized as opposed to child-sized.
