The legendary B-movie writer-director Samuel Fuller once told me about a script he had written called
The Bag Man. The title character is a bag man for the mob, a functionary whose job is to deliver packages but never to look inside them. One day he makes the fatal mistake of looking inside. He takes the money and runs.
Explaining the real novelty of his story, Fuller said with mounting excitement, “You’ve seen movies about a man on the run. You’ve seen movies about a man and a
woman on the run. But you haven’t seen a movie about a man and a woman and a KID on the run!”
