No, they wouldn't. The way the Hays code worked, nothing that exceeded the content of a PG film would have been allowed, even by the standards of that time.
Look, I'm not saying that a gory movie is, in and of itself, a horrible thing (I would have to turn in my Dead collectors club card if that were the case
). But I have been holding this film to a very, very high standard, mostly because the original Lon Chaney version is my all-time favorite Universal Monster film, hands down. I am just profoundly disappointed that they took the new film in the direction they did, rather than truly honoring the original.
