* Creator/BurtLancaster and Nick Cravat both started out as acrobats, so they do all the stunts their characters do in the movie. Not only that, but most of them are done in long shots and long takes, which aren't easy to fake anyway. And they are *all* awesome to watch.
* For the lethal surprise LaResistance prepares for Gruda's festival, Professor Prudence engineers Creator/LeonardoDaVinci-[=esque=] war machines such as cannon carts, a proto-machine gun with multiple rifles and even a [[FireBreathingWeapon flamethrower cart]]. And he basically invents nitroglycerine.
* Humble Bellow's HeroicSacrifice allows Vallo's ruse to board Gruda's ship to work.
