Cowboy Bebop at His Computer: The story Closet got a lot of attention from the British tabloids. Most of them did not do the research, believing it to be a story about Dredd being gay (in reality, he's a Celibate Hero), as opposed to what homosexuality in the 22nd century means for ordinary citizens of Mega City One.
God Does Not Own This World: Dredd was originally conceived by John Wagner (writer) and Carlos Ezquerra (artist), but copyright and publication rights lie with Rebellion (at present). Plenty of other writers regularly write new material, but an unofficial understanding exists that only John Wagner is allowed to alter the status quo.
Keep Circulating the Tapes: Or the back issues, rather—four installments of "The Cursed Earth" epic are missing from The Complete Case Files due to a legal dispute over representations of pretty much every fast food chain that existed at the time. The front page of the volume in question hastily sums them up. Thankfully, as "Cursed Earth" is a very episodic story, losing the chapters doesn't hurt its pacing any.
From the film:
Creator Backlash: Stallone, as a fan of the comic, isn't happy with how the film turned out, feeling that much potential was wasted.
However, some of the dumber ideas (such as the infamous kiss with Hershey) were Stallone's.
John Wagner wasn't happy with how this film turned out.
