I don't know if it's that simple at this point. What is going to fundamentally change until we have a vaccine that we're able to mass distribute? Even then, there are still a lot of unknowns about the effectiveness of a vaccine. Especially in the States, we do not have this thing under control and it's going to be Fall/flu season before we know it.
IMO, this movie will not come out this year. We could be looking at late 2021 or even 2022. But by then, theaters may be out of business. That's the aspect that is getting overlooked by a lot of people. It's a real catastrophe.
Nolan is probably guilty of being overly optimistic about how soon it was going to be to safely re-open, and it's understandable and unsurprising that he was taking that stance given that you could argue his life's work in a way has been based around fighting for the continued viability of the traditional, theatrical film model and older ways of making and distributing movies in general. There was a period where it look like we had flattened the curve, before the recent spikes. But today's article is still reporting on conversations that happened months ago. It's a rapidly evolving situation, but ultimately his opinion isn't that important. As I've been saying over and over again, the studio is responsible to make the decision here.
Rather than everyone constantly trying to dunk on Nolan, it would be much more productive to start having real, hard conversations about what the future of the industry is after this, at least in the film loving community. The impacts are going to be far beyond this one film. I think it's highly questionable at the moment whether we see anything major release in theaters next year, too. Sorry, The Batman.
