So Bogart was unimpressed by a film, that he probably never saw the finished movie because he was terminally ill and died the same month it was released.
Well, we really have no idea. I don't think we can say for certain what he saw and didn't see, can we? They finished filming a full year before he died and held it for a domestic release at Christmas 1956, eleven months later. That doesn't necessarily mean that no one involved got to see and form an opinion of it prior to that.
