Inside Llewyn Davis, directed by the Coen brothers in 2013. Just over an hour and forty minutes long. Very good film, and a little different from the Coens' usual themes.
Edit: My bad, I thought the title referred to the film made most recently that you saw instead of the last film you saw. In that case, it'd be GoodFellas. To be honest, I thought it was a very good film, but I wasn't overly impressed like most seem to be.
