Alright... let's have em. 3 lists: Top 5 hotties you wanna be with, top 5 alternates for those, and top 5 one night stands. My wife and I kinda came up with this and have gotten several others to do it as well.
Keep in mind that we're mainly talking people of celebrity status here, so if you name someone that is not well known, please state who they are. And the first list is based off of both looks and characters they've played, as well as any interviews you may have seen them in (basically looks + personality). The alternates fall in the same line (I guess you could consider the first two a top 10 list, but we like it the other way). The third list is people you may not particularly like, but just want to bone.
Mine (not specifically in 1-5 order):
Top 5:
1) Courtney Cox
2) Naomi Watts
3) Gwen Stefani
4) Reese Witherspoon
5) Angelina Jolie
Top 5 Alternates:
1) Catherine Bell
2) Diane Lane
3) Kate Beckinsale
