Blue Valentine has been the most powerful film I've seen at Sundance so far, and with standout performances from Michelle Williams and Ryan Gosling, it feels like it'll be pulling in some big awards at some point. It's not the cheeriest film in the word (think Revolutionary Road), but it's an extremely realistic look at both the best and worst parts of a relationship. We'll have a review up soon, but the Sundance synopsis is: "On the far side of a once-passionate romance, Cindy (Michelle Williams) and Dean (Ryan Gosling) are married with a young daughter. Hoping to save their marriage, they steal away to a theme hotel. We then encounter them years earlier, when they met and fell in love -- full of life and hope."

We sat down at Sundance with Ryan, Michelle, and director Derek Cianfrance to talk about the film, which takes place through flashbacks to the past when Cindy and Dean first met, and how they're doing several years later.
