In a day and age when literally everyone connected to a film production gets a credit, from craft services to on-set teachers of child actors to random “production babies” who didn’t even work on a film, it is utterly incomprehensible that vfx artists, whose work makes possible the final images that appear onscreen, are routinely omitted from screen credits.
I can attest to this, having worked in the field. Most of the work in TV and cinema goes uncredited, with team leaders or just the post houses at most being recognized with an end credit placement (by contract, of course). I understand totally that it is always a team effort and hardly any of the viewing public sits through the entire end credits roll. I totally get it. But when it happens that you are included, that small token of recognition does remind you why you're doing 12-hour days erasing power lines, making day look like night, adding/removing people and/or signage from shots they weren't supposed to be in and pushing greenscreened people in front of moving cars.
He's also a producer in all his films. He definitely has the clout and oversight to ensure its done. But he's also a luddite and so it's not natural for his brain to consider things like that. Remember, this is a guy that doesn't even have a mobile phone.
I mean, there are also production offices, editors, post-production supervisors, and Universal's contract with DNEG involved.
If he missed it, then so did dozens of other people. Though the fact that DNEG just laid off like 8% off their workforce in London makes me think that it was a deliberate decision from the studios rather than "Nolan forgetting to do it"
As a director and writer, he wants his name to to be seen, to tell people it's his film. As a producer, he makes sure the actors appear in the correct order. After that, it's someone else's problem.
Surely as an actor and director, those people that were integral to achieving his vision getting the recognition they deserve should, ordinarily, be his problem?
And from the article you posted elsewhere, the "Luddite" term comes from his children because he doesn't use a smartphone. Which he basically says if he had one it would negatively affect his creative productivity. I don't think that's unreasonable.
There's also nothing inherently wrong with practical effects and film stock. On top of that, the practical effects he uses in camera are rarely untouched by digital vfx
There's still no defense for leaving work uncredited
