Filmmaker Roy Pace has told Radio 4's The Film Programme how he turned back time for the Man of Steel in 1978's Superman. After several attempts had fallen through he had a crack using a cheap globe purchased from Woolworths.
Pace ran a company called Camera Effects which specialised in, well, camera effects. In a world before CGI they produced commercials and film titles using chemicals and rostrum cameras.
I’m not sure a Woolies globe was quite as cheap as Pace says it was, but it might emphasise his prophet margin when he claims director Richard Donner paid £15,000 for a first take rush. At the very least, the idea that an iconic scene came off the shelf of a high street shop is kind of cool.
