Christopher Walken. More COWBELL!
It is, I think, difficult to separate the importance of a man or woman's physical appearance from their successes in the film and television industries, but Christopher Walken is SO distinctive in appearance and VOICE, that he is destined to be a Lifetime Achievement Award winner at some point in his life.
He is, by the way, EXTREMELY talented as well. On stage he has performed in many Shakespearean plays. I can't say if he is "typecast" or not, but for the most part he plays villains, somewhat...creepy villains. Who knows where he may next appear? Look where he has already been:
Saturday Night Live Host (seven times so far) with his own "Best of Christopher Walken" SNL dvd
Movies: Annie Hall, The Deer Hunter (Oscar for Best Supporting Actor), Catch Me If You Can, The Prophesy, The Dead Zone, The Dogs of War, A View to a Kill, King of New York, The Wedding Crashers, Pulp Fiction and many, many more. I counted 98 films in the internet database.
And how amazing is it that Christopher Walken is known as the guy who can yell, "More Cowbell!" and instantly get a laugh, no matter where he says it. He is such fun to watch.
