Trivia: Rover Dangerfield
- Actor Allusion: Rover continues to make jokes and remarks when he's depressed. Rodney Dangerfield became a comedian to cope with depression.
- Descended Creator: In addition to playing the lead, Rodney Dangerfield co-wrote and produced the film, and even wrote the lyrics to the songs.
- Executive Meddling: According to animation historian Jerry Beck, Rover Dangerfield was originally conceived as an R-rated comedy which more accurately captured Dangerfield's standup routine, but was retooled as a kid-friendly version to compete against Disney.
- Hey, It's That Voice!: The kid is Dana Hill in her Max Goof voice.
- What Could Have Been: Again, this was originally conceived as an R-rated animated film that would have more faithfully captured Rodney's raunchier stand-up material. Considering that this was a few years before "South Park" would define what counted as animation specifically made for adults, one wonders what kind of impact a film like that could have had.
