Doing It for the Art: Say whatever you want about the quality of the movie, but it really was a labor of love by Don Oriolo. The Felix series was all but dead by the time it was released, and his dad was too ill to make a new Felix movie, so Don took it on himself to get a Felix the Cat movie made just to carry on Otto Messmer and Joe's legacy and revitalize interest in the character. Even in spite of its box office failure, it at least succeeded in its goal of getting people interested in the Felix franchise again.
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, 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 the elderly Joe was ill and 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.
