Plot: An attractive woman (Natalie Portman/Mila Kunis) and her attractive friend (Ashton Kutcher/Justin Timberlake) decide to have casual sex without attachments.

How to tell them apart: One has the Acadamy Award-winning actress from "Black Swan." The other has the actress she made out with in "Black Swan."

Winner: "No Strings Attached" disappointed, but Timberlake can be funny. There's hope for "Friends."
