The trailer for Thanks for Sharing has hit the web, and in it Gwyneth Paltrow stars as a woman who falls in love with a sex addict, played by Mark Ruffalo. Apparently she also does a sexy striptease in the film ... who knew!?

When the movie premiered at the Toronto Film Festival in 2012, Gwynnie told The Globe and Mail, "There's a line in the movie where somebody says something like, 'Isn't sex addiction just an excuse men use when they get caught cheating?' But actually, it is a real pathology. It was interesting to learn about it, see what the behavior is and what causes it, and how people are sober. It was very interesting. I learned a lot."

It does sound like an interesting movie! Josh Gad, Joely Richardson, Tim Robbins and Pink also star in the film, which is set to be released in September.
