The Shrek opening sequence subverts fairy tale conventions by having Shrek say "like that's ever going to happen" after a typical fairy tale opening. It establishes the film as a comedy through its upbeat music. Scenes of Shrek's daily activities like showering and brushing his teeth in vulgar ways, and being hunted by humans, reveal him as an outsider who prefers his solitary life as an ogre. The opening credits creatively reflect the characters, like John Lithgow's villain credits using maggots to portray him as horrid versus Cameron Diaz's princess credits being more appealing.
