Los Angeles: Hollywood's celebrated director Christopher Nolan has said that he recreated nuclear explosion without using Computer Generated Imagery (CGI) techniques for his new flick 'Oppenehimer'.
"I think recreating the Trinity test (the first nuclear weapon detonation, in New Mexico) without the use of computer graphics was a huge challenge to take on," Nolan was quoted as saying by 'Variety'.
The upcoming film is based on the life of nuclear physicist J. Robert Oppenheimer, who is regarded as the 'father of the atomic bomb'.
"Andrew Jackson, my visual effects supervisor, I got him on board early on and was looking at how we could do a lot of the visual elements of the film practically, from representing quantum dynamics and quantum physics to the Trinity test itself, to recreating, with my team, Los Alamos up on a mesa in New Mexico in extraordinary weather, a lot of which was needed for the film, in terms of the very harsh conditions out there there were huge practical challenges," said Nolan.
'Variety' adds that Nolan went on to call 'Oppenheimer' a "story of immense scope and scale".
He said: "It's one of the most challenging projects I've ever taken on in terms of the scale of it, and in terms of encountering the breadth of Oppenheimer's story. There were big, logistical challenges, big practical challenges.
"I had an extraordinary crew, and they really stepped up. It will be a while before we're finished. Certainly, as I watch the results come in, and as I'm putting the film together, I'm thrilled with what my team has been able to achieve."
'Interstellar', 'Dunkirk' and 'Tenet' cinematographer Hoyte van Hoytema reunited once again with Nolan for 'Oppenehimer' and the two managed to get IMAX to create a new kind of film stock for them.
'Oppenehimer' is set to arrive in cinemas on July 21, 2023.
