[1] The film is inspired by the murder of Dee Dee Blanchard[2] and stars Marcia Gay Harden, Emily Skeggs, Brennan Keel Cook, Garfield Wilson, Kayla Deorksen, Heather Doerksen, and Tate Donovan.

On January 27, 2019, a "special edition" of the film was aired that featured behind-the-scene interviews with Harden and Skeggs.

Camile Stoller (Marcia Gay Harden) is the mother of a sickly girl named Esme (Emily Skeggs).

Harden was not aware of Blanchard's murder and had not heard of Munchausen's syndrome by proxy, whereas her co-star Emily Skeggs was familiar with both as she was a fan of true crime.

[4] While filming Skeggs spent about two and a half hours each day getting the bald cap applied to her head while Harden had to wear body padding for portions of the movie.
