We can't imagine a world where Bob Saget didn't play Danny Tanner, but the original unaired "Full House" pilot was actually filmed with a different actor playing the family patriarch. Apparently, producers wanted Saget from the start, but he was filming "The Morning Program" at the time, so comedian John Posey was cast instead. However, after the pilot was filmed, "The Morning Program" was cancelled, Saget became free, and Posey was let go. As Posey explained during an April 2014 interview with Yahoo! TV, "Nobody said there were problems. It seemed like everything was fine. We shot it. I learned as much as I could in a short period of time. And next thing I know, 'Hey, you're no longer employed.'"
