Hidden Secrets From Behind the Scenes of Bonanza

11. Dan Blocker was a tough guy on and off the set

Eric "Hoss" Cartwright was often the source of many jokes and buffoonery, but he was always reliable when it came down to it. Dan Blocker, who played Hoss, was just as tough as his character.

During filming, Blocker's horse threw him to the ground, snapping his collarbone. Rather than interrupting the shoot, Blocker simply set his bone himself and continued filming. Once filming wrapped, he sought medical attention and spent six weeks recovering.
