A double bill of CGI chipmunk madness. 'Alvin and the Chipmunks' (2007) is a live action, big screen outing for everyone's favourite Chipmunks - Alvin, Simon and Theodore. Discovered and adopted by struggling songwriter Dave Seville (Jason Lee), the dynamic trio decide to join forces and embark on a singing career, performing Dave's songs. When success beckons however, unscrupulous record company boss Ian Hawke (David Cross) decides that he could make a lot more money from the boys if Dave was out of the picture. In the sequel 'Alvin and the Chipmunks 2' (2009), when Alvin (voice of Justin Long), Simon (Matthew Gray Gubler) and Theodore (Jesse McCartney) are forced to put aside their music superstardom and go back to school, they are given the challenge of saving the school's music department by winning the $25,000 prize in a battle of the bands. But the Chipmunks unexpectedly meet their match in three singing female chipmunks known as The Chipettes: Brittany (Anna Faris), Eleanor (Amy Poehler) and Jeanette (Christina Applegate). Romantic and musical sparks fly in the face off that ensues between The Chipmunks and The Chipettes.
