Fan Casting Who Censored Roger Rabbit?

Eddie Valiant is a hardboiled private eye, and Roger Rabbit is a second banana comic strip character. The rabbit hires Valiant to find out why his employers, the DeGreasy Brothers, who are owners of a cartoon syndicate, have reneged on a promise to give Roger his own strip and potentially sell his contract to a mystery buyer. Evidence shows that there was no mystery buyer and the reason Roger Rabbit remained in a secondary role was because of his lack of talent. Soon after, Roger is mysteriously murdered in his home. Now, it's up to Eddie to find the killer, through a series of twists, turns, double crosses, and trekking through the criminal underbelly of Toon Town...
