There are references to the Portal video game series. At one point Mother asks Daughter if she would like cake (similar to the cake referenced throughout Portal). Later in the film, Daughter's jumpsuit is tied around her waist revealing a white tank top, which is almost identical to Chell's outfit.
Director Grant Sputore said of the casting of Hilary Swank in this film: "It is a privilege to welcome Hilary Swank to our film. She is a remarkable performer who always brings tremendous commitment and honesty to the screen. I'm excited about the journey ahead with Hilary and the talented Clara Rugaard".
