Other movies have incorporated The Wizard of Oz into their fabric, notably Woody Allen's Annie Hall , Martin Scorsese's After Hours and David Lynch's Wild at Heart , not to mention the popular book/Broadway play Wicked, which tells the story from the Wicked Witch's perspective.
Lynch has also felt compelled to douse the movie (which took the prestigious Palme d'Or at Cannes this year) with an unending flood of references to "The Wizard of Oz."
Though far from an intellectual exercise, the film fiddles consciously with big cultural archetypes—Elvis, Marilyn Monroe, and The Wizard Of Oz, among others—and with capital-letter depictions of Good and Evil.
Wild at Heart takes the archetypal road movie and adds inventive variations including sexual intrigue, ritual murder, pyromania, dirty talk, an ensemble cast familiar from "Twin Peaks," identification with media icons, and references to The Wizard of Oz.
What Lynch seems to have been going for is a sort of white-trash variation on "The Wizard of Oz" -- one that's been left out in the sun to rot and fester and run lousy with maggots.
But among all the pop-cultural referencing laced throughout Wild At Heart, the most important, noticeable, and constant allusions in the film are the numerous ones pertaining to The Wizard of Oz, with many pieces of dialogue referring to Sailor and Lula’s journey using terminology and imagery from the classic film.
