This is quite possibly the funniest WWII movie ever.
In Italy during WW II, a patrol of American soldiers discover a space ship that has crash-landed in the woods, and they come across its alien crew. A nearby Nazi unit also finds out about the alien craft, and sends a patrol to capture it and the Americans.
I’m watching it right now, it’s only 86 minutes long. I don’t think it was ment to be this funny though. The reenactors are kind of lame, and most of the special effects suck. The guy named “Mittens” has an interesting gun. I’ll see if I can get a picture of it.
