Cleaver is very combative with Eddie Valiant in terms of who's going to solve the Acme case. One can only imagine what sort of twists a Toon human in an angry and confronted match over jurisdiction would have generated, and it's not only a good example of why this film works, but also why people have always wanted a sequel.
(Pulling out his gun and poking Valiant) “Get off the Roger Rabbit case. I got the wife pegged as the killer, and I’m an inch away from proving it. You keep poking around you’re liable to screw up my play...and that would make me very unhappy.”
