Mark Forest's bare-chested torture scene, in which he's spreadeagled beneath a cluster of dangling, about-to-drop spears, may have inspired two similar scenes. Robert Culp, in the 1967 episode I Spy: A Room with a Rack (1967), and 'Sam J. Jones', in the 1987 movie, Jane and the Lost City (1987), underwent similar ordeals.
