The poster parodies at the end, are all of movies either from Warner Brothers, its subsidiary New Line Cinema, or owned by Turner Entertainment. The filmmakers originally conceived of parodies of other famous films such as The Sound of Music (1965) and Star Wars: Episode IV - A New Hope (1977), but ultimately abandoned them because it would have required paying licensing fees to the owners.
The film was initially announced in June 1993, as a production of Lost Boys, owned by Michael Jackson and David Kirshner. A combination of live action and CGI, it would have starred and been choreographed and scored by Jackson. This version never made it to the screen. A rumor that it was to co-star Looney Tunes characters has yet to be confirmed.
According to Animator Lauren Faust, Nancy Giles was originally cast as the speaking voice of Sawyer, and many scenes were animated to her performance. Jasmine Guy replaced Giles when the project was ninety percent complete. The original voice for the character was much deeper, resulting in a noticeable contrast between Sawyer's final speaking voice (Jasmine Guy) and singing voice (Natalie Cole).
The last film for the short-lived Turner Feature Animation studio. In the midst of production, Ted Turner sold all of his companies to Time Warner, and Turner Animation was absorbed into Warner Brothers Animation.
"Dedicated to Our Friend and Collaborator, Gene Kelly", who acted as a choreography consultant (uncredited) for the film shortly before he passed away in 1996. Kelly's cement hand and footprints at the Grauman's Chinese Theater forecourt are clearly seen in the opening musical number in Hollywood as a tribute (even though he didn't place his there until 1969).
In one scene, Danny lands on a cement block from Grauman's Chinese Theater that has Gene Kelly's feet and hand prints (although he did not arrive in Hollywood until 1941, two years after this film takes place, and did not place his feet and hands in cement until 1969). This movie was Kelly's last film project.
