Finally some news! The first audition date for Halloween Horror Nights 21 has been set! Mark your calendars for July 12, 2011! It looks like it's going to be a little different this year. It appears that you've got to schedule an appointment with Universal to audition. It's most likely due to the overwhelming amount of applicants in the years past. Unfortunately the sign up link hasn't been posted yet.
