Eli: “Ten years from now you're gonna be having sex with your wife. And it's gonna be in the missionary position. And one of you is going to be asleep.”
Vanilla Sky made popular the term f**k buddy; then came the movie. But the no-strings sex enjoyed by Ashton Kutcher and Natalie Portman gets more complicated when he falls for his coital companion. Ghostbusters director Ivan Reitman leads a solid cast, also including Kevin Kline and Lake Bell, but a decent "friends with benefits" theme is pretty much ruined by an over-reliance on crudity to provide the laughs instead of the script.
