Rutger Hauer has Died

I haven't seen many of Rutger Hauer's films, but I loved Ladyhawke, and was impressed with his performance in Bladerunner. He was the bad guy in the film of Buffy the Vampire Slayer, which led to the long running series. And the Guinness commercials were fun. He appeared in many films and TV series, in English and Dutch.
In his personal life, he was an environmentalist, and set up and AIDS awareness organisation called the Rutger Hauer Starfish Association.
I've just heard that he's died, aged 75.
