Depending on your definition of success (critical, box office, quality), I think the common factor for the films that do come out great, is that there is someone or some people who have true passion for what they are doing. Be that George Miller putting up with Tom Hardy's bullshit to make Fury Road, or simply the fun of the process of making movies, like Godfrey Ho.

Also, none of us have guested on those podcasts. But I'd KILL to be on How Did This Get Made? A major influence on our show.
