Dead On Arrival

In the opening sequence of the classic Western One Upon A Time In The West there are three gunmen who show up at the train station. “Stony” (Woody Strode), “Snaky” (Jack Elam) and “Knuckles” (Al Mulock). Towards the end of the four day shoot Mulock jumped from the balcony of his room on the second floor of his hotel room in Gaudix, Spain wearing his costume. Mulock survived the fall, and before being taken away by an ambulance, Sergio Leone shouted, “Get the costume, we need the costume!” Mulock suffered a pierced lung from a broken rib and during the bumpy ride to the hospital he died. Sergio outfitted a crew member to finish the shoot and in several of the iconic shots of the trio standing on the platform you can see “Knuckles” looks a little off.

No one knows the reason for his suicide, but one of the crew members later claimed Mulock was a drug addict and committed suicide out of desperation, because he couldn’t acquire drugs in the isolated location where they were filming.
