As far as I know, no actors have been hired or rehearsed. Only the stunt company designing the stunts have been rehearsing in a sound stage in california. It's unclear if they've run through it here in Florida yet. Those stuntmen and women helping to develop the show will train the actors in Florida once the venue is ready. We will know when they're auditioning for the show because it will be posted on Universals Audition website.
