Demi Moore, 61, plays an aging Hollywood star in the trailer for The Substance, described as a ‘feminist horror’ film directed by Coralie Fargeat (Revenge). The film, which debuted in Cannes and earned the best screenplay honors, features Moore embracing a secret cloning procedure to save her career.

The trailer sees Moore’s character, Elisabeth Sparkle, fired as the celebrity host of a daytime TV exercise program by a network producer (Dennis Quaid) and facing replacement by a more youthful and beautiful star.  This leads Elisabeth to inject the black market ‘secret serum’ dubbed The Activator, which produces a younger, more perfect version of herself called Sue (played by Margaret Qualley). The problem is Elisabeth’s two selves can’t get along, as the Activator requires her to spend one week in one body – and then one week in the other.

The Substance will hit theaters on Sept. 20; see the trailer – here.
