Roy Huggins developed the series with Wayde Preston in the part of undercover government agent Christopher Colt, who takes the cover of a traveling
Old West pistol salesman, hence the title of the series.
Colt .45 also featured fictionalizations of actual historical characters, including
Edwin Booth (brother of
John Wilkes Booth, the assassin of
U.S. President Abraham Lincoln),
Sam Bass,
Billy the Kid,
Lew Wallace,
Judge Roy Bean,
Buffalo Bill Cody,
Ned Buntline, and
Calamity Jane. as Sam Colt Jr., in 1959 During this period,
Colt .45 was one of several ABC/WB Western productions, along with
Cheyenne,
Sugarfoot,
Lawman,
Maverick, and
Bronco. Various series leads occasionally did
crossover episodes on some of the other WB programs. One of the most imaginative was the
"Hadley's Hunters" episode of
Maverick, in which Bart Maverick (
Jack Kelly) comes upon Christopher Colt's sales satchel, abandoned in a room and covered with dust, as the series had been cancelled the previous season. In 1958, series star Wayde Preston left the series because he claimed he was made to do stunts that required a
stunt man. Preston was also reportedly unhappy with the show's low budget, which caused other problems. Because of Preston's departure, producers were forced to air repeats of the series along with a few new episodes to complete the 1958–1959 season. After leaving the series, Warner Bros. prevented Preston from obtaining other acting jobs. He eventually returned briefly to the series, but was demoted to a co-starring role with May. Due to the casting changes, the series was eventually marketed in the
United Kingdom as
The Colt Cousins. ==Guest stars==
