The New York Times

In addition to his six episodes of The X-Files, Donat is also known for playing the doctor who treated J.R. Ewing after he was shot on Dallas' famous cliffhanger episode. “He had an easy gravitas as a performer and seemed to come from that generation that took the art seriously but not too seriously," David Duchovny said of his TV dad.
