1. The oven brand in the opening scene is called, "Hotternell," HA!
2. And the "director" of the film, Raoul J. Raoul, is played by IRL famous film producer Joel Silver.
3. A bunch of cows are lined up in front of a sign that says, "Cattle Call" — which is an old-fashioned Hollywood term for casting auditions.
4. Steven Spielberg, one of the film's producers, makes an animated "cameo" — you can see a drawing of him in the background of the third photo Roger has in his wallet.
5. There's also a "hidden Mickey" on the same wall above and to the right of Spielberg.
6. Also, you can see Roger and Jessica are meant to be dining at the famous Brown Derby restaurant — as noted by the Brown Derby wall sconces.
7. There's a Betty Boop doll on Teddy's (Eddie's brother) desk.
8. There's also a photo of Eddie and his brother as kids working as circus clowns — this setup pays off at the end of the film when Eddie uses his old clowning ~skills~ to distract the weasels.
9. The Dip ingredients used to kill toons is a mix of turpentine, acetone, and benzene which are actual paint thinners — so, the Dip LITERALLY erases animated characters! :-(
10. And the shoe that gets "dipped" was voiced by Nancy Cartwright (aka Bart Simpson!) — although, she went uncredited.
11. Roger and Benny the Cab are voiced by the same actor, Charles Fleischer.
12. The tunnel to Toontown is the same tunnel director Robert Zemeckis would later use in Back to the Future Part II, which came out the following year in 1989.
13. And there's a sock and buskin (comedy and tragedy masks) symbol made from Felix the Cat's face above the tunnel entrance.
14. Eddie's toon gun comes in a box inscribed by Yosemite Sam that reads, "Thanks for getting me out of the Hoosegow."
15. The truck Eddie crashed into in Towntown says, "Acme Overused Gags" and carried things like bowling balls, bananas, and a piano.
16. There's even a pair of Mickey Mouse's...SHORTS?
17. Also, there's a salon for HARE cuts in the background here with the image of a hare about to be decapitated.
18. There's a message written on the men's room wall that Eddie hides in that says, "For a good time call Allyson 'Wonderland' — the best is yet to be."
19. If you have a dirty enough mind, these posters in the ~seedy~ Toontown alley are...QUESTIONABLE.
20. There's a "Cartoony" newspaper with the headline, "Bob Z Has A Winner" — a reference to the film's director Robert Zemeckis.
21. And, hey look, you can see Cinderella's glass slipper in the background here!
22. When the toon train hits the Dip Machine at the end of the movie, the windows in the train depict scenes of death and violence.
23. And finally, Kathleen Turner — who famously provided the speaking voice of Jessica Rabbit — actually went uncredited!
