Behind the scenes

 * The Eighth Doctor's first outfit was a costume of the famous lawman and gunfighter Wild Bill Hickok. This version of his incarnation fulfills the actual role of a lawman and gunfighter, who was also shot to death like Hickok.
 * The name "Doc Gallifrey" is a reference to John Henry "Doc" Holliday, an American dentist and gambler who participated in the infamous 1881 "Gunfight at the O.K. Corral" in Tombstone, Arizona.
