We Asked: Which Dexter cast member picked up an actual weapon on accident when filming a scene?
ANSWER: During filming, Jimmy Smits (Miguel Prado) accidentally picked up a real knife that had been left on set instead of a prop knife and stabbed stuntman Jeff Chase in the heart. Miraculously, Smits hit a small plastic cover that had been affixed to Chase, and Chase was badly bruised but otherwise uninjured. Chase later noted that they had done 10 takes of the scene–where his character was tied up and about to be killed Dexter-style by Smits’ Miguel Prado–and Smits had only hit his mark with the prop knife in two of them. Yikes! Source.
