Before he became an award-winning and world-renowned director, 'Hugo's' Martin Scorsese had slightly more humble film beginnings. Actually, a lot more humble.

To the young and naive Scorsese, the film was a big deal, but it was just another B-movie in a long list of B-movies for its producer Roger Corman.
