He's like a handsome German guy (although he was Dutch), perfectly equipped to be your best nightmare. One of my favorites was a movie in which he played a psycho terrorist who attempted to blow up the UN Headquarters. People take a funicular to Roosevelt Island and he was on a rampage to disconnect one of the cars so it would plunge into the East River, thereby killing everyone on board.
He was thwarted of course, but it was fun while it lasted. I can't even begin to remember the name of the film, must have been made in the 1980s'--yeah. Nighthawks it was called. He was also in LadyHawke, but I never saw that. A friend was commenting on how much she liked him in that.
Blade Runner is ok. I guess I was never that fond of it, and I realize that's heresy but I much preferred the more nuanced book. He's like a cartoon villain in that film.
