Question: Is the documentary "The Bluffs Butcher" based on James Tillis, the boxer who was known as "Quick" due to his fast hand speed or Ron Stander, who challenged Joe Frazier for the heavyweight championship in 1972? 

full_context: Document 1: Buster Douglas: James "Buster" Douglas (born April 7, 1960) is an American former professional boxer who competed from 1981 to 1990, and 1996 to 1999. He is best known for his stunning upset of Mike Tyson on February 11, 1990 in Tokyo to win the undisputed heavyweight title. At the time Tyson was undefeated and considered to be the best boxer in the world, as well as one of the most feared heavyweight champions in history due to his domination of the division over the previous three years. The only casino to make odds for the fight (all others declining to do so as they considered the fight such a foregone conclusion) had Douglas as a 42-to-1 underdog for the fight, making his victory, in commentator Jim Lampley's words, "The biggest upset in the history of heavyweight championship fights." Douglas held the title for eight months and two weeks, losing on October 25, 1990 to Evander Holyfield via third-round knockout, in his only title defense.

He won the WBC title in 1986 after stopping Trevor Berbick in two rounds, and added the WBA and IBF titles after defeating James Smith and Tony Tucker in 1987.
