Also a fan of Rutger's.
Seen "Soldier of Orange"? Not SF, but a great flick.
Also check out his fine portrayal of Lord Vortigern in "Merlin" one of the better retellings of the Arthurian Legend, with a spectacular cast of heavyweights: Sam Neill, Isabella Rosselini, Miranda Richardson, John Geilgud, Helena Bonham Carter, and Martin Short (don't laugh, he's a great dramatic actor).
