The Shelf of Movie Languishment: The film technically was finished as early as 1987, but was left locked away for years until someone decided to dig it out and release it. Why they didn't take this extra time to touch up on the film's flaws (especially the glaring animation errors and lack of sound editing) is anyone's guess.
Talking to Himself: Peter Newman as Wack Lizardi and Pim. It doesn't happen with Wack and the Duke of Zill, though, as Wack only makes a speech about the Duke before the Duke briefly speaks to everyone in the audience.
Throw It In: The line of the monster quoting "A Streetcar Named Desire" was ad-libbed by Don Oriolo, who provided his voice.
While Don Oriolo wrote the script, he originally wanted his father, Joe Oriolo, to direct the film. But Joe was old and felt he was in no shape to be making a feature length Felix the Cat movie, so he passed on the responsibility to Don to direct the film.
