If you loved Genghis Khan, the Blue Wolf to the Ends of the Earth and Sea, try Fort Graveyard

What Fort Graveyard is

Here's a war movie that's also a bit of a goof. A demoted sergeant gets sent to whip a band of musical misfits into fighting shape in China at the tail end of WWII. It's a comedy that doesn't forget to be sad, which is a neat trick.
