The Substance is the newest body horror to hit theaters, and it is a brilliantly scathing review of Hollywood beauty standards. Directed by Coralie Fargeat, The Substance fits within her typical style of creating worlds that are recognizable, yet detached from reality. The film, which was the result of a joint venture between production companies in France, the United Kingdom, and the United States, originally premiered in May this year, before gaining theatrical release on September 20th.
