The film was shot in just 10 days.

The film was shot entirely on the iPhone 7 Plus in 4K using the app FiLMiC Pro.

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.

All of the hospital scenes were filmed in Pomona, NY at the Summit Park Hospital that recently closed.

During the scene where Nate leads a group discussion in the common room, Steven Soderbergh's film Full Frontal (2002) is playing on a TV in the background.

The film had its world premiere at the Berlin International Film Festival on February 21, 2018.

Juno Temple played a character named Violet, which is her real life middle name.
