If this movie did not have Jimmy Stewart and Spencer Tracy, the film wouldn't have even merited a score of five. It was a very uninspiring and forgettable wartime film made several years after the war actually ended. It just seemed like all the energy was missing from the film. In fact, about the only energy came from Sidney Greenstreet's pet bird--now that bird can act! Another problem with the film is the idea of casting Spencer Tracy in the role of a selfish, devil-may-care smuggler in Alcatraz at the beginning of the film. The believability of the performance didn't improve once he made it to Malaya. This is actually the sort of role I might have expected for Clark Gable or maybe even Errol Flynn (yes, I know he was with a different studio), but for Tracy, an actor who often was cast as the priest or nice guy, it just wasn't terribly convincing. Plus, he just acted too nice to be as seedy as they described him as being.
In the end, the only interesting thing about this film is how so much money was spent on the cast and so little bang was achieved for MGM's buck. This is purely a time-passer or film for those devotees of Stewart or Tracy.
