Robert Stack wrote in his biography Straight Shooting [page 259 of the paperback edition] that Joseph Wiseman was a fine actor, but trained to work on the New York stage with props; he was not accustomed to real Hollywood sets. In a 1960 Untouchables episode, he was supposed to take an axe and smash up a brewery. He hit a real pipe, the axe ricocheted off the metal, and cut through his Achilles tendon. "I never felt so sorry for anyone in my life," Robert commented. They wrote a part for Joseph as a crippled, renegade chemist a few weeks later in The Antidote which Robert noted "was one of our half-dozen top shows."
