* MultipleLanguagesSameVoiceActor: In the German version, Luca Marinelli (Nicky) dubs himself. Averted in the French version with Booker, who is voiced by Boris Rehlinger even though Matthias Schoenaerts speaks French and has dubbed himself into French before.

** [[ZigZaggedTrope Zig-Zagged]] with Andy, Joe, and Nicky. As all three characters are from nations that no longer exist[[note]]Scythia, the Seljuk Empire, and the Republic of Genoa respectively[[/note]], they technically can't share national origins with their actors, but Nicky is still played by an actor from his state's modern-day successor, Italian Luca Marinelli. In contrast, Joe is from what is now Turkey or Iran but is played by Tunisian-Dutch Marwan Kenzari, and Andy is from what is now Eastern Europe or Central Asia[[note]]though, given that she's much older than Scythian culture, her true origins could be elsewhere[[/note]] but is played by American-South African Charlize Theron.

* TroubledProduction: Rucka wrote the first screenplay, but when Creator/CharlizeTheron came aboard, she had a number of issues with it, which were raised in a conference call that he referred to as "one of the worst experiences of my career". He did a rewrite, but was fired, describing the process as "frustrating, but that's Hollywood". Theron's production company commissioned a screenplay rewrite from two new writers, but Creator/{{Netflix}} and Skydance hated ''that'' version, and director Gina Prince-Bythewood reached out to Rucka for help as filming began. Eventually, Netflix and Skydance fired the other two, then hired Rucka back to rewrite the rewrite of his rewrite, and he was on set for most of the filming. During this time he and Theron got to know each other better, and were able to work out their previous differences when she realized he "wasn't acting like a standard prima donna writer, complaining about someone ruining their story". In particular, she raised the issue that one scene was too reminiscent of the stairway fight from ''Film/AtomicBlonde'' (in which she sustained several injuries), and when Rucka not only agreed with her but wrote a new scene overnight, any reservations she had about him vanished.

* AdaptationDeviation: The twist of [[spoiler: Andy losing her immortality as Nile joins]] is not in the original comic, as [[spoiler: Andy remains immortal at the end and intends to meet Booker in a century. The film leaves the matter somewhat ambiguous, with Andy moving much more naturally than when she'd been wounded.]]

* TechnologyMarchesOn: In centuries past, it was easier for the team to fly below the radar. The twenty-first century, however, has lead to an increase in the ubiquity of modern surveillence systems and record-keeping, not to mention smartphones. Andy at one point offers to take a photo of a group of vacationers just so she can delete the picture one of them just took which had her in the background.
