ALVIN AND THE CHIPMUNKS is a hilarious adventure packed with toe-tapping tunes and fur-flying fun! When struggling songwriter Dave Seville (Jason Lee) opens his home to a talented trio of chipmunks named Alvin, Simon and Theodore, they become overnight music sensations. But a greedy record producer (David Cross) intends to exploit the ''boys'' and send them on a grueling concert tour just to line his own pockets. Now Dave must use a little human ingenuity-and a lot of 'munk mischief-to get his family back before it's too late!.
