Don Sinclair Davis PhD was an American character actor, theatre professor, painter and captain in the United States Army. He was perhaps best known for playing General George S. Hammond in the Canadian-American military science fiction television series Stargate SG-1, , and earlier for playing Major Garland Briggs on the television series Twin Peaks . In the TV show MacGyver, he was the stunt/photography double for Dana Elcar. He was often mistaken for Elcar, and vice-versa. Davis did appear in two episodes of MacGyver, as a different character each time. His first appearance was as a cement... truck driver in the episode "Blow Out", and his second appearance was as the poacher Wyatt Porter in "The Endangered". He also played Dana Scully's father in the series The X-Files. Canadian audiences may also be familiar with Davis thanks to his appearance in one of the famous Heritage Minutes, in which he played an arrogant American gold prospector who pulls a gun on Mountie Sam Steele. He also played the role of the Racine Belles' manager in the movie A League of Their Own.
