Quinn Martin (The Fugitive, The Streets of San Francisco, Barnaby Jones) produced this failed pilot, which stars Roy Thinnes (The Invaders, The Norliss Tapes) as Diamond Head, a secret agent who must stop double agent from stealing a chemical weapon.

He also goes by Johnny Paul, with his cover of being a gambler and ladies’ man living in Hawaii. The double agent, known only as Tree, ends up being Ian McShane.

France Nuyen (Alma from Battle for the Planet of the Apes) is in this, which is ironic, as she was also in the 1963 Charlton Heston movie Diamond Head. She’s joined by Zulu (Kono Kalakaua from Hawaii Five-O), Ward Costello (Bloody Birthday), Eric Braden (Victor from The Young and the Restless) and Eric Christmas (The Changeling).

It was directed by Jeannot Szwarc, whose strange resume saw him making all manner of movies from The Devil’s Daughter, Bug and Jaws 2 to Somewhere In Time, Supergirl and Santa Claus The Movie.

You can watch the Mystery Science Theater 3000 version of this movie on Amazon Prime and Tubi. It’s also on YouTube.
