American character actor Denver Pyle (The Andy Griffith Show, The Dukes Of Hazzard, and hundreds of other things) used the money he earned as an actor to speculate in oil. He would buy the rights to dry wells, betting that technology would improve to the point where the remaining oil in the wells could be extracted. He won the bet, and made more money from his speculation than his acting.
