The Thomas Crown Affair

Rene Russo, 54: The lissome Russo was a successful fashion model for years before launching into acting, and boy did she make a splash in the '90s, in films like "Get Shorty," "Lethal Weapon," "In the Line of Fire," and "The Thomas Crown Affair" (there's currently talk of a ... moresequel). She's gotten lovelier as she's gotten older. Of her nude scenes in "Thomas Crown," she has said, "It never really dawned on me that gee, I'm 45 and I'm taking off my clothes. For me it was a matter of living inside the character."
