One-trick ponies?

There's a funny and half-a-thought provoking piece at FilmWad that looks at actors who have spent their entire careers playing variations of the same character. Topping the list is Bruce Willis, who has made a mint from roles as a flinty retribution-seeker with a soft side but, alas, there's no mention of "The Sixth Sense" ...which turns the piece's premise on its ear.

And no Christopher Walken?

C'mon....
