Kate Mara and Elliot Page had been wanting to work together on a project for some time. When they couldn't find any active projects to join, they decided to produce their own. They found Joe Barton's script, which had been in developmental limbo for eight years.
For years, Kate Mara had refused to do true nude scenes. She had done brief scenes in the past where she was nude but didn't actually show anything, but it wasn't until she started working with her friend Elliot Page on this film that she not only agreed to be naked, she agreed to have sex on screen with another woman (at the moment of making the movie Page still publicly identified as a woman). When talking about the experience in an interview, she noted that it was all natural, because she and Page were so comfortable with each other and they felt they had an instant connection and trust.
First feature collaboration between Elliot Page and Kate Mara, but their second collaboration overall. They had previously starred in the True Detective (2014) parody Tiny Detectives (2014) from Funny Or Die.
Elliot Page came out as an LGBT actor in 2014.
Elias Koteas and Kate Mara worked on the Movie Shooter.
