All Through the Night (1941) - This one you need to see

You can look up the plot elsewhere, but it involves Bogie battling against an organization of Nazi fifth columnists during World War II. I will just say that if you have not seen this one and you are a fan of old movies, then you need to. In my opinion, it was one of Humphrey Bogart's best. It combined humor and drama a la Damon Runyon. Several actors of German origin are used in various roles, mostly bad guys; but Kaaren Verne (one of Hollywood's great classic beauties) is the heroine.

It has an all-star cast with several of the great character actors in Hollywood history, the action is fast, there is an endless stream of great one-liners and an outstanding musical score. The pace stays frantic enough that the movie seems longer than it is. It has a slam-bang finish. Well worth the price of admission. If you want to entertain your kids with a great movie with a compelling look at a slice of real World War II history, this is the place. The end will make you want to stand up and cheer for the good old USA. When Bogie's boys come crashing into the fifth columnist meeting, it is HERO TIME!
