The anti-DEI crowd claimed the casting of Elliot Page and Lupita Nyong'o would sink the film.
A personal caveat: While the mental gymnastics of the right-wing are as ridiculous, as they infuriating; it also needs to be said that Christopher Nolan is anything but a leftist. This article here does a good job to delve into Nolan's political bend.
I think left-wing people should also be upset with this movie as well. Just not for the reasons the right are.
Specifically because Christopher Nolan had gotten permission from Italy to use environmentally protected locations for filming, and then proceeded to dump plastic skeletons into them. But good luck finding any non-Italian new outlets talking about this.
