They also tend to be extremely versatile and avoid type-casting. I'm thinking a good example would be Tom Wilkinson who in the last decade or so has played Cornwallis, Benjamin Franklin, Carmine Falcone in two Batman movies, Friedrich Fromm and a Roman Catholic Exorcist...among many other roles. Excellent and hugely underrated actor.
I've seen the name but couldn't picture him. Did a search and don't recognize him. Don't see that many movies, though.
