The film is about a woman in Hollywood with a serious drug addiction as well as a host of other problems.

Sienna's been largely out of sight recently, starring in a play on Broadway last winter and spending time with her reunited beau Jude Law!

Of course, in addition to appearing in the film, Sienna's also back in the papers -- She's joining fellow Brits Steve Coogan and Chris Tarrant in suing Rupert Murdoch's paper, News of the World. A recently filed lawsuit alleges that a private investigator working for the paper hacked into her cell phone!

I bet he saw some pretty saucy sexts!
