You left out Lori Loughlin, Drew Barymore and Brooke Shields you...you...leaver-outer of totally hot chicks you!
Anyhow, I went with:
Molly Ringwald - wasn't she in at least half the movies made in the '80s?
Lea Thompson - such a cutie
Phoebe Cates - see above
Deborah Foreman - for Valley Girl and the Waxworks movies
Tawny Kitaen - who cares if she was in any movies, I chose her for that Whitesnake video
