Re: Fatal Flaw?
LOL, nice one dmizzo - The problems in "Casablanca" exist because there are two letters of transit that have gone missing. Letters of transit that Lazlo was going to use to get to America. Everyone wants those letters, but it is Lazlo who is driving the pursuit towards them (both because he is in Casablanca and because he wants them for his own self-interest). Strasser is actively trying to prevent that from happening (Antagonist). Once Lazlo gets those letters, the problems in the story are resolved and the film is over.
The Main Character - the one we experience the story through is Rick. Through him we get to feel what it is like to be someone who goes from an attitude of not sticking their neck out for anyone, to someone willing to take action for the benefit of others.
