The actor Rock Hudson stormed out of an early screening of ‘2001’ shouting: ‘Will someone tell me what the hell this is about?’ At film’s end, most of those who stayed did not have a definitive answer – but, as the Starchild turned majestically towards them, many felt an unmistakable tingle up the spine.
Over the preceding two hours and 20 minutes, Kubrick had explored themes that come together brilliantly in his grand finale. In space, Man finds himself at an evolutionary dead-end – it was simple ‘natural selection’ for HAL to try to replace his creator. Tools were always, essentially, extensions of the human body. If that evolutionary route leads to disaster, the next step forward for humanity can only be spiritual.
Then what happened? Maybe the Starchild returns to Earth and reincarnates as a new Buddha or Messiah. In AC Clarke’s novel, ‘2001’, s/he detonates a nuclear warhead that, perhaps, destroys the Earth. We prefer Kubrick’s ‘open ending’.
