Marion Cotillard Topless, Swimming For 'Rust And Bone' (PHOTO)

Here's one way to get your foreign film distributed in America: feature a gorgeous, Oscar winning actress swimming topless.

Marion Cotillard is in the midst of shooting the French film, "Rust and Bone," and was caught taking a naked dip on set by photographers on Wednesday. As alluring as the idea of the 36-year old stunner is, though, there's way more than just some gratuitous nudity going on in the picture.

Taken from a series of stories by author Craig Davidson, the film at least in part seems based on "Rocket Ride," which is about an marine park orca trainer who loses his leg and then joins Unlimbited Potential, a support group made of addict-amputees. Cotillard, as can be seen in photos at the Daily Mail, is wearing green socks so that post-production has a clear shot at making her an amputee on film. Last week, she was seen filming with show orcas.

Cotillard appeared this summer in the whimsical "Midnight in Paris," in this fall's less whimsical "Contagion," and will be seen next summer in "The Dark Knight Rises."
