In memory of Arthur C. Clarke. It's a long clip, but worth it.
I saw this movie with my Dad at the drive-in, in a double feature with Fantastic Voyage. My Dad stayed up to watch Raquel Welch in FV, but fell asleep during this. I stayed awake, rapt, trying to figure out what the hell was going on. Finally had to read the novel to get it.
HAL's staring red eye still gets to me.
