Ken Curtis, who would later play Matt's deputy, Festus Haggen, plays Kyle Kelly in this entry. He had previously played Festus in Us Haggens (1962).
Although Ken Curtis plays a different character other than Festus, he still wears the same loud, jingling spurs.
Ken Curtis shares scenes with Burt Reynolds. Reynolds was a semi-replacement for Dennis Weaver: Most episodes featuring Reynolds didn't feature Weaver. Once Curtis signed up as Festus, both Weaver and Reynolds had quit. So in a way, Reynolds shared those scenes with his future replacement.
