Mr. Baldwin had been sitting in a wooden church pew, rehearsing a scene that involved “cross drawing” a revolver and pointing it at the camera lens, Mr. Souza said, according to the affidavit. Mr. Souza said that he had been standing beside Ms. Hutchins “viewing the camera angle.”A revolver pointing directly at the camera lens would, of course, require dummy rounds in it. Sounds like the dummies here weren't in the chambers where they belonged, but standing around on set, handing each other guns.
