Not bad at all!
Kelly's Heroes* is a touchy subject at my table: a great heist movie, but SO MANY games get sidetracked when someone starts quoting Oddball. (Just like D&D games and
Monty Python and the Holy Grail, I suppose.) Running it "serious" and using characters from other media sounds like a good screen from the inevitable comedy.
*Just turned 50 this year! Did we have this linked already?
