Ice Age is a 2002 American animated adventure comedy film produced by Blue Sky Studios and distributed by 20th Century Fox. The film was directed by Chris Wedge and co-directed by Carlos Saldanha from a screenplay by Michael Berg, Michael J. Wilson, and Peter Ackerman, based on a story by Wilson. It features the voices of Ray Romano, John Leguizamo, Denis Leary, Goran Višnjić, and Jack Black. Set during the days of the Pleistocene ice age, the film centers around three main characters—Manny (Romano), a no-nonsense woolly mammoth; Sid (Leguizamo), a loudmouthed ground sloth; and Diego (Leary), a sardonic smilodon—who come across a human baby and work together to return it to its tribe. Additionally, the film occasionally follows Scrat, a speechless "saber-toothed squirrel" (Wedge), who is perpetually searching for a place in the ground to bury his acorn.
