I'm not sure specifically which 'guy with short arms' you mean in American Horror Story. It could be a minor character that was part of a particular storyline in one of the seasons. Maybe it was a character created by the show's creators to add to the overall sense of horror and unease. Each season has its own set of characters with various odd features.
To know who plays Elizabeth Short in American Horror Story, you'd need to look at the cast list provided by the show's producers or search on authoritative entertainment websites. It can vary depending on the specific season or iteration of the show.
Maybe it was due to budget constraints or creative decisions by the producers. They might have felt the story could be told effectively in a shorter span.
No. There's no evidence that Elizabeth Short's story has been specifically referenced in American Horror Story. Each season of the show has its own unique plot and themes that are mostly the product of the show's creative team's imagination.
Most likely not. The 'American Horror Story' franchise has a specific format for its official content. Since 'Pepper American Horror Story' isn't something that has been widely promoted or mentioned in relation to the official franchise, it's improbable that it is an official part of it.
I don't think so. I've never heard of 'Margary American Horror Story' in relation to the official American Horror Story series. It might be a made - up or misnamed thing.
