Alvin & the Chipmunks: Struggling songwriter Dave Seville (Jason Lee) opens his home to a talented trio of chipmunks named Alvin, Simon & Theodore & 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 & a lot of munk mischief to get his furry family back before its too late. Ice Age 2: Manny the woolly mammoth, Sid the sloth, Diego the saber-toothed tiger, & the hapless prehistoric squirrel/rat known as Scrat: those sub-zero heroes are back! Manny may be ready to start a family, but nobody has seen another mammoth for a long time; in fact, Manny thinks he may be the last one. That is, until he miraculously finds Ellie (voiced by Queen Latifah), the only female mammoth left in the world. Their only problem: they cant stand each other. Oh, & Ellie somehow thinks shes a possum! Ellie comes with some excess baggage in the form of her two possum "brothers" Crash & Eddie (voiced by Seann William Scott & Josh Peck), a couple of daredevil pranksters & cocky, loud-mouthed troublemakers. Manny, Sid, & Diego quickly learn that the warming climate has one major drawback: a huge glacial dam holding off oceans of water is about to break, threatening the entire valley. The only chance of survival lies at the other end of the valley. So our three heroes, along with Ellie, Crash & Eddie, form the most unlikely family as they embark on a mission across an ever-changing, increasingly dangerous landscape...
