Also, Karloff would phone it in when he thought the material was beneath him, while Lugosi always gave 100%. To back this, I specifically site the two films where it's generally agreed that Lugosi upstaged Karloff: The Raven and Son of Frankenstein. Both were films Karloff did not respect, and he blurs into the background, while Lugosi triumphs.
So you really don't think Tim Burton's "Ed Wood" has any influence at all on who people prefer nowadays?
Lugosi memorabilia outsells Karloff's simply because
there's far less of it
nor was he able to do as wide variety of roles as Karloff....he could be dramatic, tragic, comic, grandoise and even touching at times
Often times you get the impression that Lugosi had no idea what he was even saying since his annunciation is so off the mark.
Who do you prefer between Vincent Price and Peter Cushing?
