The Professor would be better cast as the guy Ruby Rod says is stone cold deaf, and who eventually rolls a billiards ball back to Bruce Willis's character (I'm drawing a blank on names this morning).
If anything, Bender would make a better Ruby Rod and could cast Roberto as the flaming bad guy entity.
Hermes would make a good Zorg.
Alrighty, I'm thinking way too much into this. 😅 I'm stopping now.
