William Eugene Burrows, known professionally by his stage name Billy Drago, was an American television and film actor. Drago's films, in which he was frequently cast as a villain, included Clint Eastwood's western Pale Rider and Brian De Palma's The Untouchables. He also had recurring roles in the television series The Adventures of Brisco County, Jr. and Charmed.

Pale Rider is a 1985 American Western film produced and directed by Clint Eastwood, who also stars in the lead role. The title is a reference to the Four Horsemen of the Apocalypse, as the pale horse's ghost rider (Eastwood) represents Death. The film, which took in over $41 million at the box office, became the highest-grossing Western of the 1980s.
