Trivia

Linda Evans went to Barbara Stanwyck's house, at 1017 North Beverly Drive, Beverly Hills, every Saturday to work on the scenes together, to the point where Linda began to think of Barbara as her mother.

According to "Wildest Westerns Magazine", Peter Breck was able to draw his gun in 16/100 of a second, making the character of Nick Barkley the fastest draw in television history.

The jailhouse set was the same one used in Gunsmoke (1955).

There was originally a fourth Barkley son, Eugene (Charles Briles), who appeared in eight episodes of the first season. Briles was forced to leave the show midway through the first season because he was drafted by the U.S. Army. After leaving the regular cast, Eugene never returned in later seasons, even when Briles mustered out of the Army, and basically, Eugene was never really referred to again.

Victoria (Barbara Stanwyck) is the only Barkley who was never shot throughout the run of the series. Heath (Lee Majors) was shot the most, while Nick (Peter Breck) was shot twice in the same episode.
