Roger Rabbit is the titular deuteragonist of the 1988 hybrid feature film Who Framed Roger Rabbit and the main protagonist of the short films and comics spun off from it. Roger is the titular anthropomorphic rabbit of the film—a frantic, over-anxious type who sometimes stutters (even while he is screaming). He is also based on the most famous cartoon characters who were popular during the Golden Age of Hollywood animation.
