Re: If Kras hadn't been killed in "Friday's Child"....
Apparently Andrews was approached to be the main Klingon in "Trouble with Tribbles", but couldn't do it due to other commitments
Would that be "The Teeth of the Barracuda,"
the pilot for The Mod Squad
? It was shot in 1967 (though the regular series began production in 1968).
