Box Office Bomb: It cost about $30 million to produce, but only made $1.5 million in profits. Parental protests over the film's Vulgar Humor after it received a PG rating led to it being pulled from theaters within weeks of its release. Part of a long series of bombs for Atlantic Releasing Corporation.
Colbert Bump: The movie might have been rightly forgotten had The Nostalgia Critic not reviewed it early in his run. Perhaps ironically, he and his brother have repeatedly stated that this is their least favorite movie ever.
Creator Killer: Director Rod Amateau never took helm of another major project after this film. It was also part of a massive series of flops from the film's distributor, Atlantic Releasing Corporation; the company's only commercial hit after this film was Teen Wolf Too, and even then it was critically panned. The amount of losses from this film and the company's other high-budget bombs (like 1969) caused the company to cease operations in 1989.
Mark Newgarden, the creator of the cards, openly called this the worst film ever made, saying that neither he nor Topps had any involvement and he was "...sick and depressed throughout the whole thing."
"I had nothing to do with this movie, I'm proud to say."
Cast member Jim Cummings also went out of his way to join the protest against the film's theatrical release when he saw the final product, an effort that eventually saw the film pulled from theaters.
Franchise Killer: This did NOT help the actual card collection at all. It now mostly exists as a niche collectors series. It also got, combined with more parental protests, an already-completed Saturday Morning Cartoon canceled before it could even debut.
Mid-Development Genre Shift: The film was originally intended as a straight horror film, but Executive Meddling tried to turn it into a ... "family film", which doesn't explain why the script maintained the Kids abhorrent homicidal behavior, or the fact that the other Kids were executed for being ugly in the Back Story.
Star-Derailing Role: Anthony Newley's already-crippled cinematic career went down the drain with this film. It had taken him nearly twenty years after the utter failure of an earlier vanity project that cost a film studio millions and had been panned as an utter flop. He never appeared in another major film for the rest of his life.
Unintentional Period Piece: The film makes no effort to hide its 1980s setting, complete with all the bizarre fashion trends of the time.
What Could Have Been: There were plans for a new GPK in the early 2010s which dissolved by 2013. Notably, it would have been the feature directorial debut of stop-motion animator PES (of "Fresh Guacamole" fame).
