In the novel, Jessica was an immoral, up-and-coming star, and former comic character with whom her estranged husband (comic strip star Roger Rabbit) became obsessed. She is re-imagined in the film as a sultry, but moral, cartoon singer at a Los Angeles supper club called The Ink and Paint Club. She is one of several suspects in the framing of her husband, who is a famous cartoon star accused of murder. She is voiced by Kathleen Turner, who was uncredited for her role. Amy Irving was cast to sing "Why Don't You Do Right?" (a blues song made famous by Peggy Lee) for Jessica's first scene in the movie. According to animation director Richard Williams, other than being a feisty-redhead female human toon temptress, she deeply loves her husband Roger. She even calls him her "honey-bunny" and "darling. " She claims that he makes her laugh, is a better lover than a driver and that he's "better than Goofy" after Roger attempts to save her from Judge Doom and the Toon Patrol. As proof of her love, she tells Eddie that she'll pay any price for Roger and she even helps prove him innocent by helping in the investigation.
