How fucking ironic - I just read this while watching the first season of 24 when Dennis Hopper appeared as Victor Drazen. My wife asked me earlier today if he was still alive and quite frankly I thought he was already dead - then I come here and read he had died. A bit spooky if you ask me.
Yeah, this sucks and he'll be missed. Dude had battled prostate cancer for a while.
