In Shrek the Third, three empowered fairy tale princesses rescue the ogre from an evil Prince Charming in the final scenes of the movie.
In this case, the ogre is the hero, the handsome prince is evil, and a group of damsels in distress discover they can take care of themselves, with too many witty takeoffs on other fairy tale assumptions along the way to mention.
You can see that lovable ogre Shrek in 4-D, be chased by the fearful Mummy in Revenge of the Mummy or get scared in Universal's House of Horror which was voted one of America's best haunted attractions by Hauntworld Magazine.
In the Shrek movies, these twisted sub-plots and familiar fairy tale characters help engage us in the trials of a grouchy but loveable ogre and his princess/ogre bride.
His likeness -- which is a mix of human and ogre -- first appeared in the book, How the Grinch Stole Christmas!, which later became a popular holiday television special by the same name.
