Robert Vaughn plays Judge Oren Travis in the series. He appeared in Die glorreichen Sieben (1960) as Lee.
In this series, the main character, played by Michael Biehn is named 'Chris Larabee' where, in the original 1960 movie, Yul Brenner played 'Chris Larabee Adams'. Eric Close played Steve McQueen's original role of 'Vin Tanner'. Most of the other characters are based upon roles from the movies "Return of the Seven" 1966, and "Guns of the Magnificent Seven" 1969.
As "Vin Tanner", Eric Close carries a "Mare's Leg" modified 1892 Winchester rifle as his weapon of choice. This is a reference to another popular Western series, "Wanted: Dead or Alive" (1958-1961); Josh Randall, the Steve McQueen character, also carried a Mare's Leg. McQueen portrayed Tanner in the movie which inspired this series.
Chad McQueen was offered the role of "Vin Tanner" but declined, since his father Steve had originated said role in the 1960 movie. Ultimately, the part went to Eric Close instead.
An Internet fan campaign was partly responsible for CBS' decision to renew this series. A team of fans organized and coordinated their efforts through a Web site, recruiting the internet fandom in e-mailing CBS executives and affiliates and raising $5,000 of their own money for ads in Variety and USA Today thanking the producers, the cast, and the extended crew members. Patti Kleckner, a Chicago-based fan, who was part of the team who organized the campaign, offered her services as a contact on behalf of the effort. She was offered a free trip to California by executive producer John Watson to make her television debut with a walk-on part in the "New Law" episode which started the second season.
