In the part of The Big Short where they are explaining the origins of Cornwall Capital, the scene is spliced with a performance from famed Dallas band The Polyphonic Spree. If you are looking closely, you can spot the head of bassist Mark Pirro. He was nice enough to talk with me and my friend Nick Brooks about the movie and a number of other things. It is a good movie, and we take about a half an hour. We spend the rest talking about the price of copper and the time a record label payed for Mark to go to the Super Bowl.
