'Joker' Director Todd Phillips

'Joker' is an origin story for the villain in the Batman series, but director Todd Phillips says it's not a comic book movie. "It really started as an experiment, so to speak. ... Maybe you could get one of those deep-dive character study movies done nowadays in the studio system if you disguise it as a comic book film." Phillips talks about the score, working with Joaquin Phoenix, and the divisive reaction to the movie.
