"In the course of the story they come across a number of possible suspects. Among them is Jessica Rabbit, Roger's wife. Jessica is a rabbit by marriage only. She's actually an ambitious young starlet who married Roger to further her career. Now that she's been given a part in a film that she wanted, she's cast Roger aside, she doesn't care for him anymore. Roger can't see this. He's blindly in love with her and he just doesn't see Jessica for the cunning and seductive person that she really is."
Roger, Jessica, Baby Herman and Eddie Valiant all remained for the final version of the film - but one character to be done away with was Captain Cleaver, the cartoon detective threatening Eddie to stop working on Roger's case. Though it was rough pencil test animation, we do get to see some interaction between Eddie and Cleaver. Jessica may have also had some costume changes in this early version of the movie. Three different outfits were shown along with more expression sketches.
