 When Ethan wakes up tied to the chair and Brownway shoots the charge  up his nose, the hand seen holding the gun to Tom Cruise (qv)s  nose is not Eddie Marsan (qv)s, but Cruises own hand. The same  goes later when Musgrave puts the phone to Ethans ear, then Ethan  bites Musgraves hand. The hand that Cruise bit was not  Billy Crudup (qv)s, but again it was his own hand.
