Rachel Weisz: In The Fountain, a “psychedelic adult fairy tale” of a film that comes out in November, Rachel Weisz plays two different characters inhabiting three different centuries in three radically different looks, ranging from period-drama corsets and skirts to a white Narciso Rodriguez coat. In her own life, Weisz likes what she calls “mysterious, sexy clothes” that are neither too revealing nor restricting. “If I’m not comfortable, I kind of just want to lie down and go to sleep. I can’t shine in any way.” At the moment, Weisz is in Memphis with her newborn son and husband, Darren Aronofsky (who wrote and directed The Fountain), to shoot a small part in a new movie by Wong Kar Wei. “I’ll be playing a good-time girl from Memphis who’s not having such a good time. Dare I say I’ll be a bit like Britney Spears?”

Justin Theroux: In his first star turn, as a crabby and battered Hollywood director in David Lynch’s Mulholland Drive, Justin Theroux sported a head-to-toe black pompadour and a golf club. Right now, his style consists of the “full-on-the-skin mohawk” he recently sported, and “what my girlfriend calls my uniform—three pairs of pants and three shirts.” A similarly spare, downtown aesthetic should prevail in the actor’s directorial debut, a recently completed movie called Dedication, shot on location in New York. He may call it “a love letter to New York or whatever,” but don’t expect a Woody Allen patina. “I’m not particularly impressed with brownstones,” says Theroux, who’s lived downtown for fifteen years.
