Ice Age

Ice Age is a 2002 American animated adventure comedy film directed by Chris Wedge and written by Michael Berg, Michael J. Wilson, and Peter Ackerman. Produced by 20th Century Fox Animation and Blue Sky Studios (in the latter's debut film), it features an ensemble voice cast, including Ray Romano, John Leguizamo, and Denis Leary in their main roles, with Jane Krakowski, Jack Black, and Goran Višnjić in their supporting roles. Set during the days of the Pleistocene ice age, the film centers around an unlikely herd of three mammals—Manny, a no-nonsense woolly mammoth, Sid, a loudmouthed ground sloth, and Diego, a sardonic smilodon—who come across a human baby and work together to return it to its tribe.

Ice Age was originally conceived by Fox Animation Studios as a traditionally animated film, but became a full-length CGI film from Blue Sky, which had been transformed from a visual effects house to a computer animation studio. Focus shifted from making an action-adventure drama film to a more comedy-oriented one, and several writers, including Berg and Ackerman, were brought on to lighten the tone. David Newman composed and conducted the film's musical score.
