Criterion just released a little chat between Guillermo Del Toro and the Coen Brothers on Inside Llewyn Davis (out now on Crtierion blu ray and DVD, in case you hadn't heard!). As much as I think A Mighty Wind is one of the funniest movies ever, I loved this line from Joel Coen: "I think a lot of people thought it was going to be a parody of folk music, or that scene, and you can't parody folk music really. It's funny enough by itself."
