When Catherine is reviewing the security footage. If you look closely on in the elevator,on the screen it says Circa and not Eclipse. The Circa resort and casino was used as the Eclipse.
Just before the painted body slams into the ground you can see three fingers are already broken.
In the opening after the real body has been revealed in the horror house everyone has ran out except for the chained "victim" scarinactor. He is stuck chained to the wall. No horror house would do this, they would have to give him a way to get out of his chains in an emergency.
