So taking a gander at the Orlando thread and Legacy confirmed that anything on this list:
Slasher movies are an American horror staple. It's the 50 best films to ever slice, dice and julienne the human anatomy.

...or any kind of slasher for that matter ain't happening at HHN this year. Which would sadly include Candyman. Just thought I'd mention that.
Also someone else (Moddesigner23) mentioned Chilling Adventures of Sabrina is coming to the event, which doesn't sound too implausible.
