Which aging action icons are left to appear in the franchise?
Hauer was never, strictly speaking, an action lead, but 'Hobo With A Shotgun' got some great mileage out of his iconic value and the fact that he's never met a bit of scenery he couldn't chew. He could be a great antagonist to really test The Expendables... just think of his turn in 'Nighthawks'... or he could be an interesting addition to the team. Hauer is an intense physical presence in real life, and it seems like tossing him into the mix would guarantee that things stayed interesting for the cast and the audience alike.
