While this is probably the first Fritz Lang film I wasn't overwhelmingly impressed with (well, maybe Siegfried, too), it does have a couple of things that make it really worth watching. Cooper's fury as a scientist early on in the movie railing against the amount of money the government pays for the development of killing machines, as opposed to curing diseases and making the world a better place, is beautiful and gave me chills. It's an incredibly powerful expression of grief and outrage in the wake of the bombings of Hiroshima and Nagasaki (this movie came out only a year after the end of the war). Also, there's an INCREDIBLE fight scene late in the movie, in which Cooper's character (who's really a professor, and just an ordinary man, not a hardened fighter) struggles with an Italian spy. I don't think Lang is known for his fight scenes, but this one is a masterpiece. There's no Jackie Chan flying over tables, swinging on chandeliers, or kicking people through walls; instead, you have an ordinary man struggling with a somewhat superior opponent, in a very realistic, very brutal fight scene. A lot of small, practical self-defense moves I remember my dad teaching me when I was young are employed in this fight, including stomping on someone's instep and a couple of simple arm grapples. The action is extremely believable and practical, and the combat is savage, between two men fighting desperately for their lives. No one watches Fritz Lang movies for the fight scenes, but this one's really one of the highlights of this otherwise "eh" film--it's extremely well-done, and very surprising for a 1940s movie.
