I’m not sure if this will get over here–unless they also do a dub, maybe?–but Toho in Japan will be releasing a black & white version of Godzilla Minus One. They won’t just turn off the color, but will recut it and redo the lighting and so forth. Godzilla should highlight quite a lot differently in black and white, and I would definitely see this if it got here.
Speaking of, for anyone who owns Nightmare Before Christmas and is planning to watch it this weekend, try turning the color off. It really makes the details on the props pop a lot, and suits the film. It’s a pretty great alternative way to experience that classic movie.
