Regarding scientific accuracy and a critical review of Space: 1999 by Isaac Asimov, Gerry Anderson commented: ‘I think that a show that is absolutely scientifically correct can be as dull as ditch-water. But I think the point he was making was that, if you are going deep into the universe, then you can say whatever you like and that’s fine; but if you’re dealing with subjects that we have up-to-date knowledge on, like the Moon, then you ought to be correct. I think that was a reasonable criticism. But I think the problem with scientific advisors is that if you had a scientific advisor in 1820 he would have told you that it was impossible to fly and to travel beyond the speed of sound. And today they’re telling us that it’s impossible to travel beyond the speed of light. I think, therefore, they are inhibiting to a production, and since the heading is science fiction – underline the word fiction – I don’t really think there’s any place for them.’
