Searching for Approval

In both Catch Me if You Can and October Sky we encountered a protagonist who was desperately searching for his father's approval and also was searching to carve out his place in society.  It is also worth noting that both of the films is based on a true story.  Your task is to discuss the motivating factors of both Frank Abignale Jr. and Homer Hickam and what these factors drove them to accomplish.  Did either earn their father's approval?  How do you know?  Make sure to use specific examples and good writing conventions in your response (and also three hundred words).
