In four episodes, Hutchins also plays the dual role of Abram Thomas, "the Canary Kid", leader of an outlaw gang who is a dead ringer for Brewster.

In each of these episodes, Brewster is joined in the fight against the Canary Kid's plans by Christopher Colt—i.e., Wayde Preston crossing over from his role in the simultaneously produced WB series Colt .45.

Towards the end of the run, Jack Elam was cast in two of the final five episodes as Brewster's occasional sidekick Toothy Thompson, but the series was cancelled shortly thereafter.

The pilot and premiere episode, "Brannigan's Boots", was so similar to The Boy from Oklahoma that Sheb Wooley and Slim Pickens reprised their roles from the film.

Hutchins appeared as Sugarfoot in crossover episodes of Cheyenne and Maverick, and in an installment of Bronco called "The Yankee Tornado" with Peter Breck as a young Theodore Roosevelt.
