For those of you who are interested, Youtube provides several videos that analyze parts of the film. I watched one them this afternoon and it did point out some things about the film that escaped me. They're interesting. I especially encourage those who expected a shoot 'em up gangster film to view a couple of these Youtube videos. They help explain Scorsese's approach and motivation.

By the way, I thought that exchange between Bruno and Frank to be quite amusing. I also noted Bufalino's expression during the exchange; he seemed to be amused also.
