Diego (voiced by Denis Leary), Manny (Ray Romano) and Sid (John Leguizamo) return in this sequel to the hit animated movie Ice Age. This time around, the deep freeze is over, and the ice-covered earth is starting to melt, which will destroy the trio's cherished valley. So, they must unite and warn all the other beasts about the desperate situation. Drea de Matteo and Queen Latifah also lend their voices. Carlos Saldanha directs.
