>ELLEN BARKIN From some angles, she looks like the girl nobody wanted to take to the junior prom in high school. But few actresses talk or move as insinuatingly (the young Lauren Bacall comes to mind), and Barkin all but lights up Al Pacino in Sea of Love.

LAURA SAN GIACOMO So much for the sex part of sex, lies, and videotape. Her sweaty grapplings with Peter Gallagher are enough to give meaningless lust back its good name.

CHERYL LADD At 38. she’s almost ready for sex-bomb emeritus status, but if Millennium doesn’t show anything else (and it just about doesn’t), it proves Ladd hasn’t lost the heavenly attributes of her Charlie’s Angels epoch.
