Bill Murray has become a cultural staple in the US, both for his work on screen as well as his antics off. His latest film, “St. Vincent,” which just opened in theaters everywhere, shows a number of different levels of Murray– within his character of course, but pervasive in his own personality as well.

“St. Vincent” director Theodore Melfi made some time around the New York premiere of the film to chat with BDCwire about how Murray tackles the complexity of his character– a hopeless lazy drunk on the outside with a history as a veteran who cared for his ailing wife for many years. The depth of his character only reveals itself more throughout the film. Melfi goes further into other parts of the movie as well, commenting on how Melissa McCarthy grows into a more serious role and how Naomi Watts becomes a pretty convincing Russian prostitute.
