I'm not sure he's classifiable as a comedian -- although he WAS a regular on a show (I never watched) called THE MOTHERS-IN-LAW. I usually see him playing very serious types.

Stage-wise he went back to the '20s and he worked with a lot of top people. I interviewed him about his BLACK SLEEP memories a while back; then I later found out that he was a stage director and had directed Karloff in a production of ON BORROWED TIME (with Karloff as the grandfather -- a reversal of audience expectations) so I interviewed him again about that. Both times he was terribly friendly, called ME back when he thought of other things to say -- he even wrote me a couple long letters. The kind of guy who, once you locate and interview him and get an idea how nice and how knowledgeable he is, you say to yourself, "Why can't they all be like this?"
