Bob Hoskins watched his daughter learn how to perform with imaginary characters, and he had hallucination problems after filming the film.
During the filming, Charles Fresche always wore Roger Rabbit’s full costume to walk around. When he was resting in the dressing room, people in other studios saw him and said that the props of this "rabbit movie" were really extraordinary. Oops.
The son of Bob Hoskins was unhappy because he never brought home the co-star.
Some of Eddie Valint's scenes in the taxi were not performed by Bob Hoskins, but drawn with pictures.
Jessica’s dialogue was dubbed by Catherine Turner, and the voice part of the singing was in charge of Amy Owen. However, Turner was not initially listed on the cast.
Although the title of the movie is a question, there is no question mark in the title, which is considered a bad omen in the film industry.
