The fact this never received a sequel is surprising.That it hasn't after 22 years is truly amazing.
The original was a box office smash,was critically acclaimed and created two very memorable characters.A Roger Rabbit revival would make millions in licensed merchandise alone.
A sequel would write itself.Especially with CGI cartoons near killing the old 2D animation of yesteryear.
Numberous modern characters could show up such as the Toy Story cast,Wall-E,The Incredibles etc.
