Boris Karloff, Arthur Treacher, Buster Keaton, and Mischa Auer. The guy with the cigar, I'm not sure.

The guy with the cigar is Ned Sparks, and I don't think I've seen anything he actually was in (he used to get caricatured a lot in older Looney Tunes).

Hollywood will never be like it was because the people we have today are far more worried about their looks and getting reality shows than they are about actually acting and don't get me started on film today. I get pretty angry when I go see something that's advertised as a drama and it turns into a "Whoa! What'd I do last night when I was drunk? At least my friends are here to remind me. hahahah oh you guys!" Or something that's advertised as a mystery or a thriller that turns out to be a remake of a foreign film (that was put together FAR better than our version) or it turns into a complete bloodbath just because. It sucks. No one seems to care about writing or talent anymore.. ::steps off her soapbox::

I think the phrase "don't get me started" delivered unironically is like one of the leading early indicators of alzheimer's

Jerry Colonna.
