Alvin and the Chipmunks 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. Alvin and the Chipmunks: The Squeakquel Alvin, Simon, and Theodore meet their musical match after returning to school and entering into a battle of the bands competition in hopes of saving the school's troubled music program. Sent to live with Dave Seville's younger nephew Toby (Zachary Levi), the three lovable marmots decide that getting an education is more important than belting out pop tunes. But the school's music program is about to go belly up, and the only way to save it is to win the $25,000 prize in the upcoming battle of the bands. Though the Chipmunks are confident they have the songwriting skills to steamroll the competition, a newly formed singing trio dubbed The Chippettes promises to give them some stiff competition on-stage. Brittany, Eleanor, and Jeanette are indeed the real deal, and the closer the competition gets, the more Alvin, Simon, and Theodore realise that in order to win, they'll have to give it everything they've got.
