Unveiling the Terrifying Truth of "Oppenheimer"

Christopher Nolan's upcoming film "Oppenheimer" will feature a recreation of the Trinity Test, the first nuclear bomb detonation, done without the use of CG visual effects. Cinematographer Hoyte van Hoytema reveals that the team experimented with various techniques, including power-filled aquariums, metallic balloons, and objects spinning and smashing into each other. The sequence took several weeks to film, and the final elements are being kept under wraps. Nolan's commitment to practical effects has become a signature of his filmmaking style.
