I know this is a non sequitur, but after watching this new Batman last night, they're is more than enough house potential for HHN, Horror Made Here, or Fright Fest. Idk the warner relationship with universal rn, but the riddler would be great character for HHN. Additionally, the film definitely feels horror adjacent in a way unlike most Batman films, so I think it stands a much better chance than another cape film
Warner wanted to bring back Horror Made Here this year, but aside from a few Instagram comments from them I don't think anything else has come out. Would love to see it come back and have them take a stab at something (The) Batman related.
