The only time that Michael Dunn and Victor Buono worked together on screen, each having previously played a recurring villain on The Wild Wild West (1965), respectively Dr. Miguelito Loveless and Count Carlos Manzeppi, with Buono also having played a different villain, Wing Fat, in a first-season episode and yet a different character, Dr. Henry Messenger, in the second return TV movie of that series, More Wild Wild West (1980). The two actors had each also been previously nominated for a Best Supporting Actor Academy Award--Buono for What Ever Happened to Baby Jane? (1962) and Dunn for Ship of Fools (1965).
