I love Bogart, most of the cast, and old films in general, but they really blew it with this one.
It was too "jokey", too slapstick. Nazis getting conked on the head, wisecracking mobsters in mortal danger, etc.
Conrad Veidt and the baddies were trying to play it straight and put some drama in this movie, but the others (due to the poor script) were just not taking any of it seriously.
Comic relief is great in tense situations, but they WAY overdid it in this film.
I even liked Dark Passage better than this one, and that is saying a lot.
