Blue Sky Studios, Inc. is an American computer animation film studio based in Greenwich, Connecticut. It is a subsidiary of 20th Century Animation, a division of Disney Studios Content. The studio was founded in 1987 by Chris Wedge, Michael Ferraro, Carl Ludwig, Alison Brown, David Brown, and Eugene Troubetzkoy after their employer MAGI, one of the visual effects studios behind Tron, shut down. Using its in-house rendering software, the studio had worked on visual effects for commercials and films before completely dedicating itself to animated film production. The studio's first feature, Ice Age, was released in 2002 by 20th Century Fox. In 2019, the studio was acquired by Disney, upon their acquisition of 21st Century Fox assets. Blue Sky has produced 13 feature films, with its latest release being Spies in Disguise on December 25, 2019, and their next release being Nimona on January 14, 2022. Ice Age and Rio are the studio's most successful films, while Horton Hears a Who! and The Peanuts Movie are its most critically praised films. As of 2013, Scrat, a character from Ice Age, serves as the studio's mascot.
