@joefromchicago,
I agree with you, Joe, re:
To Have and to Have Not only insofar that the film bears virtually no resemblance whatever to the Hemingway novel except for the title and the names of the major characters. Other than that, it's a pretty good original flick, imo, and should have been released under a different title without any royalties going to ol' Ernie 'Emorroid. As for
Key Largo and
The Petrified Forest, both were originally stage plays and the film-scripts stay fairly close to the original story lines, so I don't see how you can say that one is a remake of the other.
