This article contains spoilers for Alita: Battle Angel.

Alita: Battle Angel has been in cinemas for a couple of weeks now and, whatever your take on the film as a whole, it certainly looks the part – taking place in a richly detailed dystopian future world inspired by the pages of Yukito Kishiro’s manga series.

Directed by Robert Rodriguez and written/produced by James Cameron in what the latter calls a “creative collaboration”, Alita is a film that’s been 20 years in the making. Cameron wrote the first draft in 1999 before getting waylaid by Avatar and its upcoming sequels, but he found in Rodriguez a kindred spirit who could help him finally realise his vision.

Clearly, making a film of this scale is a huge undertaking, requiring hundreds of artists and designers – both physical and digital – to bring Iron City and its inhabitants to life. And now, thanks to new book Alita: Battle Angel – The Art And Making Of The Movie, we’ve got a glimpse into that process. Here, Den of Geek shares some concept art and behind-the-scenes shots from the movie for your viewing pleasure.
