One of the highly-anticipated films of the year, 'Oppenheimer', hit the theatres on July 21, 2023. The film is based on the 2005 biography American Prometheus by Kai Bird and Martin J. Sherwin about J. Robert Oppenheimer, a theoretical physicist who helped develop the first nuclear weapons on the Manhattan Project. The movie also highlights the race against time that the Americans faced to complete their bomb before Nazi Germany could finish building theirs.

Nolan's latest film, based on the life of J. Robert Oppenheimer, the father of the atomic bomb, generated significant buzz for its "ground-breaking" approach. The film garnered attention for its decision to authentically recreate the Trinity Test, the world's first-ever atomic explosion, without relying on CGI effects.

But, do you know how much impact an explosion like this leaves on the environment?

IMPACT OF FILM EXPLOSIONS WITHOUT CGI ON THE ENVIRONMENT

Air Pollution

Explosions release large amounts of smoke, particulate matter, and gases into the air. These emissions can contribute to air pollution and degrade air quality in and around the filming location.

Greenhouse Gas Emissions

Certain pyrotechnic materials used in explosions can release greenhouse gases such as carbon dioxide (CO2) and methane (CH4). These gases contribute to global warming and climate change.

Chemical Contamination

Some explosives and pyrotechnics contain hazardous chemicals that can contaminate soil and water if not properly managed. When explosions occur near water bodies or in natural environments, the chemicals can leach into the ground or runoff into nearby water sources, affecting aquatic life and ecosystems.

Disturbance to Wildlife 

Explosions can disturb and displace wildlife in the vicinity of filming locations. Animals may be frightened, and their habitats can be disrupted, potentially causing long-term impacts on local ecosystems.

Spectre Created Guinness World Record For Largest Ever Explosion Created On Film Set

The biggest ever film stunt explosion was captured in the James Bond movie ‘Spectre’ from 2015. The explosive scene was carefully choreographed and executed for the film's climax.  The world-record-breaking explosion happened in Morocco's renowned Atlas Mountains. It involved a significant explosion that produced a stunning blast and was captured on camera. The scene heightened the action-packed scenes in the film, which are typical of the James Bond series. 

The Guinness World Record recognized the achievement, acknowledging "Spectre" for staging the largest explosion ever filmed for a movie stunt up to that point in time. 2,224 gallons of fuel and 73 pounds of explosives, or 68.47 tonnes of TNT altogether, were used in the shot.

Later, in 2019, No Time To Die, the most recent entry in the franchise, shattered the record by using a total of 136.4 kg of TNT equivalent to film the dramatic conclusion.

How Are Explosions Created In Cinema Without CGI?

Explosive sequences in movies, particularly in action, adventure, and science fiction genres, are known to elicit excitement, thrill, and awe among viewers, but filming them is not an easy task, with or without CGI. 

Filmmakers may produce realistic and visually arresting explosions that improve the cinematic experience and fascinate audiences while ensuring a safe filming environment by using controlled pyrotechnics. Pyrotechnics must be used carefully and expertly in order to balance the entertainment value of explosive sequences in movies with professionalism and safety.

THESE SCENES IN CHRISTOPHER NOLAN'S FILMS ARE NOT CGI

Inception - Rotating Hallway Fight Sequence

In the scene, Arthur squares off against Robert's security guard in a revolving hallway with no gravity. A 360-degree rotating vertical set was put together in an airship hangar south of London to create this remarkable setup. Moreover, on this set, Gordon-Levitt and the other cast members were fastened to numerous wires and harnesses. According to Screen Rant, the cameras were positioned at the bottom of the put-together set to give the illusion that the scene is falling in zero gravity.

Pencil Trick In The Dark Knight

One such famous scene shows the Joker (Heath Ledger) giving one of his henchmen a skin-crawling death while performing a "pencil trick" for his other criminals. Stuntman Charles Jarman said, “We did a couple of half-speed rehearsals just to get the hand action of my right hand sweeping across, taking the pencil as my body was going down, and my head striking the blank surface.”

The Dark Knight Rises -Mid Air Airplane Hijacking Scene

A real Lockheed C130 Hercules intended for Bane's mercenaries for the infiltration sequences was used to tow a mock South African EMB-110 CIA jet in order to achieve the difficult midair hijack scene. In order to give Nolan complete control over the surroundings, a simulator was built for the sequences taking place within the aircraft. 

Using CGI Don't Give Threat Of Things In Real World- Nolan

Christopher Nolan recently opened up about not using CGI in explosion scene in his latest directorial, Oppenheimer. He said in an interview with Collider, “I don't want to use computer graphics because they tend to be inherently safe. They don't give you that threat of things in the real world. So the crew worked on all methods of doing things. So, we certainly did have a lot of very large explosions on set, but none of them were of the atomic variety. I can't say what it cost, no.”
