Relying on a low budget of $50K, the movie was shot over five nights in a single location with dialogue that was largely improvised.
Instead of scripts, the actors would each receive only a small paragraph (that only they would see) as their 'goals' for the day. This allowed for the story to unfold naturally and create genuine reactions in the other actors.
The actor who plays Amir, Alex Manugian, is also the co-writer. He was essentially "the mole" who helped guide scenes if the actors went astray.
When Kevin (Maury Sterling) tries to leave the house by himself, Em (Emily Baldoni) was given a note to not let him leave and his note was to leave.
The director, James Ward Byrkit, wanted to use his own house as the setting of the movie. Since his wife was 8-and-a-half months pregnant and wanted a homebirth, she agreed to let him so long as he could do it in 5 days.
