After all, by c&e, we should nominate Bela Lugosi and Boris Karloff and Anthony Hopkins as well as Peter Cushing.
I seriously considered nominating Karloff, who is one of my favorite actors, but decided to go with Cushing instead since the unspoken theme seemed to be heroic leading man types and Karloff, even when he got top billing, didn't play many "badass" roles.
Christopher Lee is another contender, but that struck me as too predictable after mentioning Cushing . . . .
I notice that Errol Flynn seems to be overlooked as well. Is swashbuckling not considered "badass" these days?
