An interesting sequel from Wolf, primarily following up the film, but also folding back in many elements and the more acidic tone of his original novel. It's overly long, with the initial plot about the production of Gone with the Wind (initially as a big musical comedy starring toons) not getting enough exploration before the second half of the book takes over with a concoction called Toon Tonic which can turn toons into humans and humans into toons. Which is a blast as a suddenly human Roger is fumbling his way through an entirely different mode of life, but because it took us over half the book to get there, this also doesn't get the development to really play the comedy of that premise to its fullest.
For those coming in from the film who haven't read the first, there's a meanness to the writing that can be offputting at times. The punches of homophobia and misogyny are authentic throwbacks to hardboiled crime novels of the past, but fly pretty fast and free here, with Eddie's gruffness falling to such repugnant levels that he's even whipping out his dick to women at a bar at one point. And did you like his romance with Dolores in the movie? Because she exits the picture quick so the author can get back to his self-insert character (Wolf literally plays Eddie on every book's cover) fantasies involving Jessica Rabbit and the starlets of classic Hollywood. We even get the introduction of Jo, Jessica's twin sister, who's identical except for the fact that she's 6.5 inches tall, just so we can perv on that scenario in multiple instances. Which is a shame, because she is otherwise well utilized in the plot as her small size makes for fun snooping and clue solving, and the best bits of the book are Eddie working through the crime with a mismatched team of Jo, Roger Rabbit, and, yes really, Clark Gable.
The side characters are a lot of fun, like Eddie getting another pair of siblings, Freddy and Heddy. Cartoon cops, an evil stunt man turned studio enforcer, Roger's evil identical cousin, Baby Herman, a jet-black shadow toon who stars in films like The Shadow of Doubt and Shadow of the Thin Man. The prose is bouncy and witty, with a big return of the word balloon shtick from the first book, where entire industries are built around either archiving or recycling these endlessly produced sources of everyday communication (my favorite being an office where the receptionists just chop their bosses words into squares and file them away instead of trying to dictate everything).
There is a lot of fun stuff here, enough that I think you could have restructured elements into a followup film. It's just darker with a more cynical humor than I was ready for, and the story really does have some frustrating pacing and construction issues. Still, I'm excited to carry on with Wolf's remaining entries.
