The animated Ice Age series tacks on a game-changing fourth act when unexpected events set the continent in motion, sending Manny (voiced by Ray Romano), Diego (Denis Leary) and Sid (John Leguizamo) away from Ellie (Queen Latifah) and the herd and into the vastness of the open sea. The world around them is forever changed, but at least one thing remains the same: their ability to make the most of extreme climate change.
