The 2001 animated DreamWorks film featuring an ogre named Shrek is Shrek.
The film follows Shrek, a solitary ogre whose swamp is invaded by fairy-tale creatures expelled by Lord Farquaad. To reclaim his home, Shrek agrees to rescue Princess Fiona, aided by the talkative Donkey. Its story combines fairy-tale settings with comic reversals and a deliberately modern sense of humor.
Shrek was directed by Andrew Adamson and Vicky Jenson and was loosely based on William Steig’s 1990 picture book Shrek!. DreamWorks developed the project after Steven Spielberg acquired the book’s rights and initially considered a traditionally animated adaptation. The finished movie helped establish DreamWorks Animation as a major rival to Pixar and Disney in feature animation.
A common mix-up is confusing the original film with the later Shrek franchise or with Shrek 2, which arrived in 2004. The first movie premiered in April 2001 and received the first Academy Award for Best Animated Feature. It also became a major commercial success, earning roughly $494 million worldwide and introducing audiences to Mike Myers, Eddie Murphy, Cameron Diaz, and John Lithgow in its principal voice roles.
