π₯ Nightmare Alley: Vision in Darkness and Light = Black & White version of 2021 film
The Wrap has an interview about the process of creating a black & white version of this film. It refers to a limited release in Los Angeles, but it is getting a wider release than that, as several theaters near me are now showing it. UK theaters are also showing this B&W version. They use the title Nightmare Alley: Vision in Darkness and Light.

I saw the color version and very much liked the eerie lighting and color, which added tremendously to the storytelling. The longer length allowed the director to flesh out some of the characters much better than in the 1947 version, in my opinion.
