Larry David

Look closely, Curb Your Enthusiasm fans — that really is Larry David in the new trailer for the upcoming HBO film Clear History.

David is nearly unrecognizable, donning a long-haired wig and a beard to play a marketing executive who quits his job just before his company's latest product becomes a billion-dollar hit. (Later in the trailer, he returns to his traditional balding, bespectacled look.)
