In the source novel for the superb blend of animation and live action that is Who Framed Roger Rabbit?, Roger doesn't figure all that much in the story. More to the point, he gets murdered and is discovered by Eddie Valiant with a speech bubble by his corpse, suggesting that he was "censored" for trying to speak out against something...or someone. The rest of the novel is Eddie investigating Roger's widow, Jessica Rabbit among others to try and work out who did it. The film, though hardly a cakewalk itself, is at least a little lighter in tone, blending cartoon elements heavily with film noir, meaning it's suitable for kids though still includes enough darkness that they'll probably end up slightly traumatised (who can forget the toxic sludge?). I'm glad we got the film we did, though at the same time, killing Roger would have been the ballsiest move in the history of children's films. Robert Zemeckis would have traumatised an entire generation of kids.
