Already adored by generations of fans, Alvin and the Chipmunks have plenty to sing about in their big screen debut-a hilarious adventure packed with toe-tapping tunes and nutty fun! Struggling songwriter Dave Seville (Jason Lee) opens his home to a talented trio of chipmunks named Alvin, Simon and Theodore and they become overnight music sensations. But when a greedy record producer (David Cross) tries to exploit the "boys," Dave must use a little human ingenuity-and a lot of 'munk mischief-to get his furry family back before it's too late!
