Spoof of 'Genesis II', HAL

Just watched this film again and recognised HAL's voice from 2001 & 2010 in the robots' voices (see the credits - it's in fact the same guy!).

When I wiki'd the film, it says 'several' SF films were parodied, though I think one that might seem obscure today was actually probably the most relevant parody reference at the time of release - 'Genesis II', a rather camp SF movie by Gene Roddenberry, creator of 'Star Trek'. He released 'Genesis II' in March 1973, and Woody Allen released the (funny, but obviously hastily made) 'Sleeper' in December of the same year. Not only is the basic plot the same (guy gets frozen in the 70's, thawed out hundreds of years later expected to save the world), but alot of the camera shots are very similar, as both movies are set in the southwestern US in the future.
