Stuntman and background player Jimmy Noel had the most appearances on this show of anybody except star Hugh O'Brian. Almost all were uncredited, and speaking parts were rare. Here, Noel gets a bit part with a few lines and three appearances on screen. Hugh O'Brian took care of his extras; Noel, Ethan Laidlaw, and others who were regulars, occasionally got a line or some camera time, in order to make a few extra dollars.
