I don't know... what was great about Price was that he could be menacing, debonair, and snidely funny all at once -- like Colicos as Kor, DeLancie as Q, or Robinson as Garak. There wasn't much room for humor in Kodos.
On the other hand, Price did play tormented, possibly murderous thespians in both Madhouse
and Theater of Blood
And, you know, he would have been perfect for "Catspaw."
