In order for the Black & White sections of the movie to be shot in the same quality as the rest of the film, Kodak produced a limited supply of their Double-X black and white film stock in 70mm. This film stock was chosen specifically for its heritage - it was originally sold to photographers as Super-XX during World War II, and was very popular with photojournalists of the era.
The Trinity detonation scene uses a combination of practical effects and digital compositing. Multiple explosions were performed practically, with a hybrid of gasoline, propane, aluminium and magnesium substances involving big miniatures. These were filmed at high speeds from multiple angles, and then layered using digital effects to create the iconic "mushroom cloud".
Matt Damon was on a break from acting as a promise to his wife, with one condition: it would go on hold if
Christopher Nolan called. As luck would have it, Nolan offered Damon the role of
Leslie Groves, and the break went on hold.
Physicist
Enrico Fermi arrives to watch the Trinity test towards the end of the film. Fermi is famous among other things for the Fermi Paradox, a thought experiment which questions why humans have never observed evidence of intelligent life elsewhere in the universe. One possible reason for this is that any sufficiently intelligent species may inevitably wipe itself out through self-destructive behaviour. The creation of nuclear weapons, especially when
Edward Teller and other physicists feared the fission bomb they were building might incinerate the planet, was one such "Great Filter" moment in human history.
