- As a publicity stunt, Paramount placed a huge cut-out of Holli Would on the D of the HOLLYWOOD sign in Los Angeles. Although they didn't have to pay any fees, the studio still had to make a donation of $27,000 to the sign's maintenance fund, another $27,000 to the Rebuild L.A. fund (this was just after the L.A. riots), and the cost of two park rangers to guard the sign 24 hours a day. The publicity stunt, however, angered local residents who picketed and demanded that the cut-out be taken down.
- In Ralph Bakshi's original script, Holli Would was named Debbie Dallas, after the porn film Debbie Does Dallas (1978).
- The original script was scrapped and re-written without Ralph Bakshi's knowledge.
- Since the characters were simply created from scratch, the directors thought it to be appropriate to parody both popular Disney and Warner Bros. cartoon characters. A few examples would be the medium used for the rabbits, the old bald man and their own version of Geppetto and Pinnochio in a larger character's stomach.
- The character of Nails the Spider is borrowed from Bakshi's own Christmas in Tattertown character Sidney the Spider. Charlie Adler provides the voices for both characters.
- Ralph Bakshi originally wanted Drew Barrymore to play the sultry 'Holli Would' .
- Traci Lords was in contention for the role of Holli Would but lost out to the more widely recognized Kim Basinger.
- The movie was originally sold as an animated/live action horror film about a cartoonist that sleeps with a cartoon and fathers a child that can travel between both worlds.
- Ralph Bakshi wanted Brad Pitt to play Jack Deebs.
