This weekend, director Ivan Reitman of such classic comedies as Stripes, Meatballs and Ghostbusters will release his newest film, No Strings Attached. In the film, Natalie Portman and Ashton Kutcher play two friends who decide to go for a friends-with-benefits situation. While it starts off as harmless fun, the duo soon realizes that there may not be such a thing as just harmless sex. While the idea of friends becoming something more may seem somewhat generic, the talented cast suggests something possibly different. So before you check out No Strings Attached this weekend, maybe give some of these under-ranked films from its stars a chance.
