Scarface is a movie with all its dials twisted up to 11. No one does lines of cocaine (a loathsome drug for a loathsome era), they do piles of cocaine; chainsaws are brandished, not switchblades; the vague, censor-baiting hints at Borgia-syle incest in the original morph here into Mary Elizabeth Mastrantonio screaming at her brother, "Ya wanna fuck me, huh, Tony? Huh?"

But Tony is a fully-fledged 1980s-style unzipped capitalist go-getter, worthy of admiration given the Friedman-fundamentalist economic fumes wafting through the zeitgeist back then; he's a Horatio Alger hero with a hole through his septum, he's Arkan in the making.

Yet another of Carter's personalities, Josh, has regressed to boyhood. He's a terrified child, one constantly fearing the wrath of his father. Again -- not entirely unlike Carter -- Josh is an image of masculinity reverted to a "harmless" or impotent stage, pre-adolescent, and therefore pre-sexual.

Finally, the guardian of the children is the personality named Margo. Importantly, Margo is female. Margo rescues Amy, destroys the Elder Dr. Nix, and restores order. It is a woman, therefore, who finally usurps the role of "hero"/"conqueror" in modern America. Carter can only become a hero when he is...female. The film's valedictory shot is of a looming, powerful Margo, standing heroically behind his family (Jenny and Amy). Carter could only be himself (a caring individual and care-giver) when in the personality and guise of a woman...and the last shot explains this visually. Margo is not menacing; not evil. She is triumphant.

All throughout this masterful, unbroken shot, Waldheim explains the history of the Nix family and the theories underlying multiple personality disorders. She basically describes the events of the movie (Cain vs. Carter) in a fashion that makes sense out of perspective we've witnessed thus far. It's a journey from the top of Carter's mind, literally, to the bottom...to Cain's mind, where we spy his murderous handiwork (the corpse).

De Palma understands that form must echo content, and so the form of his film -- multiple perspectives coming together -- reflects the flotsam and jetsam Carter's splintered mind. The virtuoso unbroken shot is Waldheim's tour of that mind, a narrative maze of twists and turns, of science and ultimately death. But importantly, this tour is an unbroken one (like Waldheim's dissertation), making linear sense of the tale for the viewer.

A: I've always loved that song and I was always disappointed by how Paul Schrader used it in the movie. He didn't really use it; he threw it in over the closing credits. I remember working at the Video Archives at the time and thinking "If I had a song like that for my movie, I'd build a 20-minute scene around it!" So I guess I did.

Q: There's a really cool sense of dislocation when that song comes on, which still sounds so modern, yet we're in World War II France. It's one of my favorite sequences in the film. It reminded me of Brian De Palma, back when he was still good.

A: When I got the idea to use it, one of the things I liked is that the song was once removed and you already knew it from something else, as opposed to something that was written for the movie. You're listening to the lyrics of the song and you're watching Shoshanna [a character in the film played by Melanie Laurent] doing all this stuff, and you sit there thinking "Wow, this song was written for Cat People, but it's totally appropriate for Shoshanna's story!" It plays like an interior monologue for her.
