Manfred the Mammoth doesn't like humans, but even he has to admit that the lost human baby he discovers is pretty cute. Unfortunately it's also in danger. Manfred and the misfit friends he picks up, Sid the Sloth and Diego the Sabre-Toothed Tiger, work together to return the human baby to his tribe before the pass closes up with snow. Along the way they come to realize the importance of friendship and what it means to be part of a herd.
Ice Age is a lot of fun and often fast-paced, but its characters are the driving force of the story. Voice cast includes Ray Romano, John Leguizamo, and Denis Leary.
