Daniels worked many jobs – cowboy on cattle ranches, miner, rodeo performer, and tour guide – before he went to Hollywood to try his luck at acting. Daniels started as a stuntman. From there he graduated to
character actor status. His title "Chief" was a Hollywood invention, a
stage name. He had the title role in
Geronimo (1939) and played
Tonto in both
Republic Lone Ranger serials,
The Lone Ranger (1938) and
The Lone Ranger Rides Again (1939). Throughout the 1940s, Daniels continued to work as a character actor, maintaining the Chief Thundercloud persona. In most of the films in which he was featured, he played an antagonist opposing the white protagonist. For example, in the film
Young Buffalo Bill (1940) he played Akuna, a renegade Native American chief who commits murder while working as a hired hand. In the film
Renegade Girl (1946), he played the main villain, Chief Whitecloud, a vengeful antagonist with a vendetta against the protagonist's family. Although featured in a number of films, Daniels was uncredited in some films, such as
Gun Smoke (1936), a film about a ranch defending itself from a flood of sheep. He also appeared in the first two parts of the serial ''
Custer's Last Stand'' (1936), again uncredited. Daniels had a short appearance on early television on
The Gene Autry Show (1950). Daniels appeared as Chief Thundercloud in the 1954 episode "The Saint's Portrait" of the syndicated
anthology series Death Valley Days hosted by
Stanley Andrews. One of his last appearances was on March 1, 1955, as the
Apache Geronimo in the premiere of the
syndicated television series Buffalo Bill, Jr.. ==Legal problems and later years==
