AMC Theatres said it is reinforcing its security procedures in the wake of today’s shooting in Colorado during a midnight screening of Warner Bros‘ The Dark Knight Rises. The company will not allow any guests into theaters “in costumes that make other guests feel uncomfortable and we will not permit face-covering masks or fake weapons inside our buildings”. Said the chain: “We’re reinforcing our security procedures with our theatre teams, which we cannot discuss in detail for obvious, safety reasons. Local law enforcement agencies, our landlords and their and our local security teams are stepping up nationwide to ensure we provide the safest environment possible for our guests. We couldn’t be more grateful for their collective support”. AMC said it is not amending any of the circuit’s screening schedules for The Dark Knight Rises but it will exchange or refund tickets for the movie.
