Box Office Bomb: Battle of the Rock Lords did poorly at the box office, making only $1,338,264.
Dueling Shows: Challenge of the GoBots was infamous for competing against The Transformers, both shows being cartoons about shape-changing robots based on a toyline and sharing a few voice actors (most notably Peter Cullen, Arthur Burghardt, and Frank Welker). Ironically, Transformers' owner Hasbro later bought Tonka, the owner of the GoBots toyline, in 1991, so Hasbro now owns the rights to what was once a competitor to the Transformers franchise.
The show featured a decent state of limbo over its legal status. In which case the rights to the TV show and likenesses of characters from the TV show are now Warner Brothers (by way of Hanna-Barbera), the general franchise as a whole is owned by Hasbro (by way of Tonka).
The Warner Archive took over releases for the show and completed it in three sets. The first containing the original mini series and two more each containing 30 of the remaining episodes.
The movie being the last piece missing which Warner Archive did confirm they own but that does contain clearence issues to be hammered out before making a release possible.
One of the Guardians is named Blaster, who shares his name with one of the Autobots from the GoBots' more successful competitor Transformers.
The Other Darrin: Cop-Tur was originally voiced by Bob Holt, but ended up voiced by Arthur Burghardt in the show's final episodes as well as the movie GoBots: Battle of the Rock Lords because of Holt's death.
Screwed by the Lawyers: The Renegade Rhetoric feature originally had a picture of Cy-Kill from the cartoon on the page, but Hasbro apparently warned the staff that Hanna-Barbera still owned the rights to the likenesses of the cartoon and so the picture was quickly replaced with an original piece of artwork.
