Sign in to your ScreenRant account The one villain who was reported to have been majorly changed as a result of Christopher Nolan's request in the oft-forgotten fourth The Dark Knight movie, Batman: Gotham Knight, does seem to have benefited from this alteration in the film overall. When it comes to the wide roster of Batman movies, The Dark Knight trilogy is arguably the first film series to spring into most minds, in part because it still defines the cultural consciousness around the hero and what his story on-screen should be like in a big way. Though The Dark Knight movie trilogy is an epic and sprawling story with a similarly large cast to suit its needs, the series does have a relatively small overall villain roster - a detail that makes sense given the need to focus mainly on Batman himself and his growth as a vigilante, but that's also left audiences curious about the many other antagonists we can assume were lurking around Gotham's alleyways in this universe. Batman: Gotham Knight did shed more light on what was possible for this universe with its own take on Nolan's DC film world, and does a relatively solid job of keeping things in line with what you would expect from an extension of this side of the franchise tonally and story-wise - though it's certainly helped by one note about what to change for a prominent Batman villain. Christopher Nolan's Reported Killer Croc Change Request Makes Perfect Sense Given The Dark Knight's Tone Batman: Gotham Knight remains a fascinating extra corner of The Dark Knight movie series that often goes overlooked compared to the central trilogy itself, despite the animated spinoff exploring scenarios set between Batman Begins and The Dark Knight in some undeniably fascinating ways. This also means the movie is able to delve into the wide Batman character roster more, especially since its own narrative is split into chapters, allowing for certain segments of the story to delve into different figures with somewhat more ease. One of the most fascinating figures of this roster is that of Killer Croc, who is a unique entity to feature in the movie given he's usually one of the more larger-than-life characters in Batman's rogues gallery, since he's usually depicted as a giant crocodile person, though more realistic depictions do exist. Interestingly, as per CBR's records of the Batman: Gotham Knight world premiere and its Q&A panel, Killer Croc's design in Batman: Gotham Knight reportedly initially came with a tail, which Bruce Timm stated Nolan requested to have removed, though he also mentioned that "for the most part they left us alone except for the Killer Croc thing". The idea that the Killer Croc design was the only detail that really came up during the production of several unique figures for the film does seem par for the course if not arguably wise for both Gotham Knight and for the broader Dark Knight series, since - while Gotham Knight is often considered quasi-canon at best - having the otherwise very grounded movie series contain someone with a crocodile tail might have felt somewhat jarring overall. Christopher Nolan's Killer Croc Change Helped Make Batman: Gotham Knight Feel More A Part Of The Dark Knight Movie Series It would have been very easy for Batman: Gotham Knight to completely go all in on its own depiction of Gotham and its iteration of the wider DC world in a way that ended up being entirely different to The Dark Knight trilogy it spins off from. Ultimately, making an animated movie larger-than-life is easier in many senses than it is for a live-action movie, especially when the comic source material itself often features depictions of people who are superhuman in their musculature or powers in some form or another. As such, the effort Batman: Gotham Knight takes to reign itself in with things like Killer Croc's design is all the more notable, and works to help keep the film feeling like an extra series of stories set in the same world as The Dark Knight trilogy, even if the movie does have its own distinct differences both visually and in terms of its narratives.
