Just because a Roger Rabbit sequel never came to pass doesn't mean that people haven't tried. They have—a lot. And, almost every time, the movie never got past the concept or script phase. One version, Toon Platoon, written by Nat Mauldin (The Preacher's Wife, Open Season) was a prequel, involving Roger rescuing his Jessica from Nazis. (Steven Spielberg, a producer on the project, didn't care for it.) Robert Zemeckis was keen on a movie that took place in the '50s, which would be a tribute to that era of film, the way the first movie paid homage to 1940s film noir. Even today's king of Hollywood, J.J. Abrams (Star Wars: The Force Awakens), took a crack at both a Roger Rabbit short and sequel in 1989.
