Pictures help.
This is a guy I remember seeing a hundred times on my TV during the '60s. Very familiar face.

Great Star Trek episode. Scared me as a kid when he turned people into those cubes and crushed one in his hands.

"This person is dead."

He was in a lot of shows, as per IMDB. Only one Perry Mason, though ( which I do remember ... from Me TV, that is! ) and I guess that picture is from his role as Rojan in Star Trek, memorable for the reduction of the crew members, at his hands, to “crystals” about the size of volleyballs.

Of course his role in Forbidden Planet was the prototype for McCoy, in Star Trek.

We watched that episode last night. Quite a surprise to see this news this morning!

Same here. I watch enough vintage TV and remember his face well now.
