Members of the cast and crew said that Walter Brennan cackled with delight when Dr. Martin Luther King, Jr.'s assassination was announced.
Television editor Stanley Frazen, who was on the set when Walter Brennan celebrated the assassination of Dr King, said Brennan later had another jubilant moment when Robert Kennedy was killed in June 1968. Frazen recalled the cast and crew were "incredulous" at the jig danced by elderly Brennan when he was told of Martin Luther King Jr.'s murder.
Will's (Walter Brennan's) horse was named "Marauder".
Dick Powell originated the character of Will Sonnet in 1955 on his Four Star Playhouse: A Spray of Bullets.
