Shrek, for instance, is a 2001 American computer-animated fantasy comedy film based on William Steig's 1990 fairy tale picture book of the same name. The film stars Mike Myers, Eddie Murphy, Cameron Diaz, and John Lithgow in the lead roles. The main character, Shrek, is an OGRE who embarks on a quest to save his swamp from being taken over by the evil Lord Farquaad. Shrek is accompanied by a talking donkey, and together they face a variety of obstacles and challenges. The term 'OGRE' is used to describe a large, monstrous, and often cruel creature, which is fitting for Shrek's character.
