Zac Efron and his “Me and Orson Welles” co-star Claire Danes swear they saw a ghost on the set of their movie. They were doing a scene in the Gaiety Theater, which is known as one of the most haunted places in the country.

The crew, of course, has been taking every possible opportunity to use this ghost sighting to their advantage by seeking out ways to spook them even more. It sounds like they are having a blast!
