Is there anything recorded on whether this paved the way for Curtiz to make Casablanca? Because it's the same film... What a goddamn fascinating footnote. How does no one talk about this movie? It's finely made, clearly a stepping stone in style toward Casablanca's masterful verve and rhythm, and I can't see how The Key didn't end up giving us that film. I'd welcome some historical perspective from those who have it.
