My list of take my money now themes:
Inception- need a keith Elwin touch for some inverted mechanics
Princess Bride- make it like MM but with a little more fun whimsical feel and the one liners have to be great.
Nintendo themed, Zelda/Mario/Metroid heavy with supporting characters.
Greatest showman-give me a circus theme a bit like Houdini had a love child with funhouse
Matrix-just dont screw it up
Top Gun-only with music being spot on and some legitimate metal plane models in there
Alice in Wonderland (neon colors very trippy with some black light multiball)
Greek Mythology (i know the Olympus one is coming from a company)
Justice league comic version-AIQ similar with a K.E and Z.Y touch
