This guy as “Dr. Nadir” was an absolute hoot, leering at the bikini girls that Mars was stealing (a weirdly popular plot in the ’60s) and yelling with relish for their space ray to be fired at “MAXIMUM…POWER!!!” If you think of John Lovitz playing in full Master Thespian mode, you’d be about 98% correct. I actually wouldn’t be surprised to learn the guy was a relative.
Of course, the Martian guys looked like this, while their Princess was played sans make-up by an early Playboy Playmate.
