The film was shot in just 10 days.
The film was shot mostly on the iPhone 7 Plus in 4K using the app FiLMiC Pro, though not entirely. For some shots, Soderbergh would use a Panasonic Lumix GH5, such as those requiring a telephoto lens or the car scenes where the vehicle would shake so much the phone would be unusable.
The budget was only $1.2 million according to "The Times".
To get the dolly shots in the film, Steven Soderbergh would hold the iPhone on a DJI Gimbal while sitting in a wheelchair and a crew member pushed him around.
The film was shot in chronological order.
