I was watching one of my YT subs today and had no idea that Nightmare Alley was a remake of a previous movie, but that version is also available for free on YT. I've downloaded it (JIC) but haven't watched it yet.
Nightmare Alley (1947) - IMDb
It did not do well at the box office back, apparently partially because the audience was confused about Tyrone Power playing such a dark character and they didn't know what to make of the movie itself. But like the current Nightmare Alley, the visuals look really interesting. Coleen Gray appearing in it doesn't hurt the visuals either.
Edit: I didn't notice until after my post that Kailo already mentioned the previous film, I just thought it was honestly an original with neo-noir visuals. I still want to see it, and remakes in Hollywood are nothing new, but I can also be Mr. Oblivious sometimes - I think I just skimmed about the mixed reviews, but great visuals.
And nothing against del Toro either, he loves his noir and horror movies.
But if anyone is still interested, the 1947 version is available on YT.
