As Hanna-Barbera was getting off the ground, John Stephenson, who would go on to become one of their most reliable actors, was getting steady work in front of the camera. Case in point is a 1959 episode of Mackenzie's Raiders.
Stephenson plays Jack Taylor in "The Hawk", in which Mackenzie (Richard Carlson) must deal with a renegade he once court-martialed (a pre-Star Trek DeForest Kelley). A twist is that the Hawk is also looking to reunite with his son, now with his mother and stepfather (Stephenson).
