I saw this on ITV's Out of this World series when I was 11. It was in flickering black and white and seemed really spooky and just like the stories in 'I Robot.' The intro music to the Out of This World series set the theme and the Boris Karloff intro was, if I remember, a bit eerily over the top. Re-reading the Asimov books again, they retain that 'sepia-tint' "could be 'Forties could be 'Fifties" 'nether-world', something that the recent I Robot film missed completely. Killing off Alfred Lanning in the first reel was a classic screw-up and lost the plot, never mind the robot. Where were Peter Bogert, Donovan and Powell for instance. Hell's teeth, the book REVOLVES around their activities and antics. Stephen Byerley doesn't even get a look-in. The film-makers went for style over substance (unlike ITV who tried to stick to the story within the limits of 1960's TV technology.) The 2004 version completely lost that 'spookiness' and pulp-SciFi ambiance that I Robot has on every page.
