 Production began with Gig Young (qv) as the Waco Kid. On the first  day of shooting, the scene where the drunk Waco Kid hangs from a  bunk asking if Bart is black, Young revealed that he really was  indeed drunk (he had had an alcohol problem for years) and proceeded  to undergo a physical collapse on set. Brooks shut down production  for a day and Gene Wilder (qv) flew cross country to take over the  role.
