The deactivation of HAL 9000, a scene that took over 6 minutes of running time, is one of the most indelible cinematic memories from my teenager years. I have never felt more conflicted with empathy for and gripped by fear of an electronic conscience since. In the scene at one point when HAL says "I'm afraid, Dave", I'd almost want to stop Dave, but I am also simultaneously aware and fearful that HAL may be manipulating the human!<p>I've watched many SciFi movies with similar themes - even ones where the artificial beings are given faces. But HAL's baritone voice and the precise controlled cadence did for evoking emotions what none could top. Douglas Rain's voice and how Kubric used is an example of craftsmanship mastery at its best!<p>RIP HAL 9000. I'll sing Daisy for you.
