Shrek is an American media franchise made by DreamWorks Animation, loosely based on William Steig's 1990 picture book Shrek!. The series primarily focuses on Shrek, a bad-tempered but good-hearted ogre, who begrudgingly accepts a quest to rescue a princess, resulting in him finding friends and going on many subsequent adventures in a fairy tale world. It includes four computer-animated films: Shrek (2001), Shrek 2 (2004), Shrek the Third (2007), and Shrek Forever After (2010). A short 4-D film, Shrek 4-D, which originally was a theme park ride, was released in 2003. Two television specials, the Christmas television special Shrek the Halls (2007) and the Halloween television special Scared Shrekless (2010), have also been produced. Two spin-off films were made centered around the character Puss in Boots: 2011's Puss in Boots and it's sequel, 2022's The Last Wish. Additionally, a stage musical adaptation was made and premiered at Broadway for more than a year.
