This show was originally developed to be adaptations of short stories and novels by the great Western author Zane Grey. However, the material ran out (the books were far too long for a half-hour show), and later original material was commissioned.
This show was unique because it was the only Western anthology on TV at the time. Anthologies were popular on early TV and were the equivalent of today's TV movies. Because of this format, it attracted many stars who wanted to appear on it.
