Charlize Theron has no qualms about taking her clothes off -- for the right role, that is.
The Academy Award winner, 36, shares the cover of W's August issue with her Prometheus costar Michael Fassbender, 35. The magazine spread features the scantily-clad actors fondling each other in a grimy warehouse.
Fassbender -- who famously went full-frontal nude for his role in 2011's Shame -- admits that "sex scenes sound like more fun than they are. Death scenes are easier, really. Maybe because I've died so many times. I've had a lot of practice. In my movies, I'm often naked or dying."
