James Cameron shares his differences with director Tim Miller concerning the final edit of Terminator: Dark Fate. Cameron said (via CinemaBlend):
I would say many. And the blood is still being scrubbed off the walls from those creative battles. This is a film that was forged in fire. So yeah, but that’s the creative process, right? I mean, my work with Robert on Alita was very different. Robert loved the script, loved everything, said, ‘I just want to make this movie. I want to make the movie the way you see it.’ I was like, ‘No, you got to make it your movie.’ I had the reverse experience with Tim, which is Tim wanted to make it his movie. And I’m like, ‘Yeah, but I kind of know a little about this world.’ So I had the matter and the anti-matter version of that producorial experience.
Miller in a recent interview with Screen Rant said:
You feel like, if there’s a railroad, the track was already laid there. So, it just happens to stop out in the middle of nowhere, and I just started laying more track. Because Jim kind of created this; set up the story, set up these characters; and I’m just sort of telling the next chapter of it.
