Dennis Quaid has acted in his share of Westerns—including as Sam Houston in 2004’s “The Alamo” and cast-out James-Younger Gang member Ed Miller in “The Long Riders.” But he’s probably better known as the tubercular dentist Doc Holliday in 1994’s “Wyatt Earp.”
And that role gave him a unique connection. In 1999, Quaid’s older brother Randy was in the sci-fi Western “Purgatory,” about a town that is a way-station between Heaven and Hell. Randy plays…Doc Holliday, the town physician who looks nothing like the earthly gunman (and nothing like the character his brother Dennis played).
