The film's unconventional stereo 3D, 4K, 120fps shooting format generated a total of 540TB of video footage, and a final delivery file of 84TB.
Steve Martin revealed in an interview that they were several weeks into the shoot before he realized that Joe Alwyn was actually English. Alwyn's American accent was so accurate that Martin didn't have a clue that he was from the UK.
The idea of shooting in 120fps along with native 4k rendering and mastering, came from an experimental film shot by Douglas Trumbull (2001 fame). Trumbull showcased his work to Ang Lee, who came back to Trumbull's private theatre for repeat viewings including his family and eventually Sony executives, who put the film into production.
Mason Lee, who plays the soldier Foo in the film, is the son of the film's director, Ang Lee.
