It was a black and white film, from the 50s (I believe). The title might have the words “gold”, “golden”, “key”, or “door”. It starred an actor similar to Ray Milland (tall, handsome guy). It was about a man who was living in a small town, somewhere in Latin America (could be in Mexico, near the US border). He had to stay there for a while, as he was not yet allowed to return to the US (was he a deserter?). He lived a relaxed life. The atmosphere of the movie was similar to that of Our Man in La Habana. Could anyone please help me?
