Jason Lee has signed on to star in the live-action/CGI animated, Alvin and the Chipmunks for Fox 2000 Pictures and 20th Century Fox Animation.

He will play the Chipmunks' dad, Dave Seville, while chipmunks Alvin, Simon and Theodore will be computer generated. The Hollywood Reporter says the film will center on Seville and the chipmunks, focusing on the trio's origins as singing sensations.

Tim Hill will direct Alvin and the Chipmunks from the screenplay by Jon Vitti; production begins at the end of this month for a December 14th release.
