Cybertron's third moon, which exists solely due to an editing error in this movie, would reappear on Beast Machines: Transformers (1999), still bearing Unicron's claw-marks.
Scatman Crothers' final role to be released in his lifetime. One more film, Rock Odyssey (1987), would be released a year after his death.
The negatives for the matted widescreen version of the film were either destroyed or lost, and for a time only the VHS full-screen version of the movie remained. The North Carolina School of the Filmmaking in Winston-Salem carries a print of the movie assembled from different reels of other prints of the movie found in its archives. The pieced-together print is in good condition. This should be noted that this widescreen version of the movie was achieved by "matting down" the original full-screen animation, essentially chopping off the top and bottom.
During production, the idea of transforming the planet Cybertron into a robot to battle against Unicron came up, and was quickly dismissed. The Marvel Comics Transformers issues, which had a separate storyline than the cartoon, had Cybertron as the planet form of the Transformer god Primus, whose backstory involved warring against the evil Unicron. There was no connection between the discarded script and the comic series, different authors came up with the same general idea independently.
