Producers Michael G. Wilson and Barbara Broccoli commented: “It is absolutely tremendous that the Guinness World Records have recognised Chris Corbould’s incredible work in ‘Sprectre’ in which he created the largest explosion ever in film history.”

Taking place in Erfoud, Morocco, the blast had a total yield of 68.47 tonnes of TNT equivalent and was the result of detonating 8,418 litres of kerosene with 33 kg of powder explosives – and it lasted for over 7.5 seconds.

I remember that scene distinctly—I’ve already seen the movie twice—and while it was extremely impressive, the thought that this was the biggest explosion in cinema never crossed my mind.
