The Canyons with Lindsay Lohan and porn star James Deen.
It was a small little indie flick, I thought Lohan and Deen did really good jobs on the movie. Doing some research after, there's a really in depth article on the production and working with Lindsay Lohan.
It's not something that I'd watch over and over again, but this was a solid film (its had some knocks as both director and writer have illustrious CVs and this isn't up there with an "all time great").
