Shok!
The film's script was inspired by a short 2000 AD comic strip called SHOK! Walter's Robo-Tale in the Judge Dredd Annual 1981. In the comic, a robot head part is recovered from the bloody aftermath of the Cursed Earth story. Controversially, the original theatrical release failed to mention the comic book despite heavily referencing its storyline. Following legal action a notice was added to later versions and the strip's creators, Steve MacManus and Kevin O'Neill, now get writer's credits.
It is now considered by some to be the first 2000 AD movie spin-off.
The comic refers to the building as the Andy Warhol artists colony.
