Rifleman Cast Notes! ✨🤠 Leif Erickson only appeared in the 1958 pilot episode, “The Sharpshooter,” as the shady town boss, not as the Marshal. R.G. Armstrong played the Marshal early on, but it was Paul Fix who made the role of Micah Torrance legendary. Erickson’s notable role in The High Chaparral wouldn’t come until 1967. | The Rifleman - the Original Series
