In page Sunset Carson:

"

Carson became an accomplished rodeo rider in his youth. For a time, he worked in a Western show owned by early cowboy actor Tom Mix. In 1940, he traveled to South America, where he competed in rodeos for two years. After his return to the U.S., he played small parts in the 1943 film Stage Door Canteen, and the big-budget 1944 film Janie, both having him billed as "Michael Harrison". Catching the attention of Republic Pictures executive Lou Grey, he was signed to a contract and given his own series of B-movie Westerns beginning in 1944, changing his name to "Sunset Carson".[citation needed]
