It is being directed by Tim Hill and being produced by New Regency Productions and 20th Century Fox. It is currently scheduled for theatrical release on December 14, 2007.

Based on the beloved cartoon series, Alvin and the Chipmunks is a family story filled with comedy, heart and exciting music. After a chance run in with the struggling song writer, Dave Seville, three very special chipmunks, Alvin, Simon and Theodore decide to make Dave's home their own. It's not long before the chipmunks realize in order to convince Dave to allow them to stay they must reveal their talent...not only can they talk but they can sing! They quickly become a singing sensation, while Dave becomes something more than their song writer; a father figure. Problems occur when the chipmunks begin to revel in their stardom and rebel against Dave. However, they soon discover that being a family with Dave is the sweetest success of all.
