Ronald Lacey (Archer Hayes) is best known for playing the sadistic Nazi villain, Toht, in Raiders of the Lost Ark (1981). Tom Selleck (Magnum) had previously been considered for the role of Indiana Jones, but was forced to turn it down due to an actor's strike and his commitment to the series.
This is the second appearance by John McCook (Nolan Atherton) in the series. He previously appeared in Season 3 "The Big Blow" (1983).
