Top Drawer !!
I believe that this movie is right up there with the best adventure movies ever made such as Treasure of the Sierra Madre and the icon Casablanca but it has not received as much credit as it deserves. The characters and acting are extremely believable- and very memorable which I think is an important test of value. Everyone remembers "Steve" and "Slim" but "very memorable" also applies to Cricket and to Eddie as played by the great Walter Brennan. Brennan should have received an academy award nominination fot best supporting actor. It is cerainly true that this movie was an attempt to capitalize on the success of Casablanca by Warner Bros. and the plot has a lot of similarities to Casablanca (all usually a receipe for mediocrity at best) but I think it worked brilliantly this time!
Incidentally, it's interesting that while 63850 IMDB users responded for Casablanca (1-10) only 3801 responded for To Have and Have Not. To me that suggests thst once a movie gets on the top 250 list (let alone the top 7) it has a huge advantage. Everyone wants to see it and it's like when you tell everyone that Picasso is one of the greatest painters ever, that's how people will rate everything he does ! Although I will admit that 3% of the Casablanca users gave it a rating of one so not everybody acts that way.
