The Substance exposes brilliantly the tortures women put themselves and their bodies through. It is bleakly true, but there’s a bigger, and happier, truth for all women.

The film follows fading A-list actress Elisabeth Sparkle (Moore) who, after being axed from her exercise segment on a morning show by Dennis Quaid’s hideous TV exec Harvey, takes an experimental substance that ‘generates a new, younger, more beautiful, more perfect, you’.

Starring as a 'fading celebrity ' (the synopsis' words, not mine), Moore plays Elisabeth Sparkle, who's fired from her TV show for being too old. Desperate not to let her stardom slip away, Sparkle decides to take a black-market drug, which is capable of creating a younger, more 'perfect' version of herself.

The female body is a horror movie waiting to happen. From puberty and the grisly onset of menstruation, in pictures such as Brian De Palma’s Carrie and John Fawcett’s Ginger Snaps, to pregnancy and childbirth — Rosemary’s Baby is the obvious example — women have provided a rich seam of inspiration for genre film-makers over the past half century.

The Substance, which stars Demi Moore and Margaret Qualley, has been billed as the feminist horror film of the year - but cinemagoers have been left horrified by its gory scenes.
