From what I've seen, European actors are willing to star in anything. Thus you have folks like Michael Caine who will happily do Jaws The Revenge on one hand, and The Quiet American on the other. Same thing with someone like Anthony Hopkins who does Freejack and then turns around and does something like Titus Andronicus.
Max Von Sydow is one of the greats, and I imagine he's proud of his career. You also have to remember that he's an old man, and he's looked like an old man since he was middle-aged. The roles you're offered get kind of limited at that point.
