Once

I too saw this film at Sundance, and we were treated to a live performance afterwards by the two main characters, who are actual musicians and not actors.

I can't say enough good things about this film. It is bittersweet and romantic, with great music (not Irish music, but the singer/songwriter type) as the two main characters collaborate on their songs and help each other become stronger and face the romantic challenges they both are suffering from. The end of the film is wonderful and Hollywood-cliché-free! I hope this film gets the distribution it deserves, because I'm going to be telling everyone to see it.
