The show was huge in Japan. It got a whopping forty-three percent rating, and became one of the most successful American television series. When Robert Fuller went to Japan in 1961, about one hundred thousand fans welcomed him at Haneda airport. During his visit, Fuller was invited to dinner with Prime Minister Hayato Ikeda. Even the Beatles did not receive such an enthusiastic welcome when they first went to Japan in 1966.
This show was unique for its time, in that the two lead characters actually "worked" on the ranch. They chopped wood, cooked, washed dishes, washed clothes, fed chickens, repaired roofs, and did all the chores necessary to run a ranch. This aspect added an authenticity to the lead roles that you didn't see in other shows.
The exterior sets of the old western town of Laramie in this series were not on the Warner Brothers backlot. They were filmed on the Universal Studios Western Street, as Revue Studios was located at Universal International Studios. Warner Brothers' Laramie Street was used in Lawman (1958) (also set in Laramie, WY), and for many years afterwards, it was also used in countless Warner Brothers movies and television projects since the end of this show. It had also been continuously rented out for filming to several non-Warner Brothers productions, such as Little House on the Prairie (1974), amongst others. Known throughout the studio as "Laramie Street", it consisted of three streets of old western buildings, and it was the last of two separate western sets to remain standing on the Warner Brothers lot. Another western street, which existed in the central portion of the studio's backlot, was demolished in the mid 1980s. Laramie Street remained in existence until 2000, when it was demolished to make way for a collection of modern-day exterior set houses.
With the 2016 passings of Peter Brown, who co-starred in Lawman (1958), and Hugh O'Brian, who starred in The Life and Legend of Wyatt Earp (1955), Robert Fuller remains one of the last living main adult male characters from a western series that originated in the 1950's. Clint Eastwood from Rawhide (1959) is another. James Drury who starred as The Virginian (1962) was the last surviving main adult male cast member, who died on April 6, 2020, however that series premiered in 1962 and ended in 1971.
The setting for this series is Laramie, Wyoming and the era the 1870s. Laramie had a population of 828 in the 1870 census and 2,696 in the 1880 census.
