One of the latest horror films to land in cinemas is so ‘graphic’ viewers have been walking out before it even finishes. Starring Demi Moore, the film premiered on 20 September and has pretty simply been described as absolutely ‘f**ked’.

The much-hyped body horror The Substance won Best Screenplay at the Cannes Film Festival, collected a string of five-star reviews (including by our very own Tim Robey) and has tipped Demi Moore for an Oscar.

The new body-horror movie "The Substance" is a wild time, It also took co-stars Demi Moore and Margaret Qualley way out of their comfort zones.

The Substance, starring Demi Moore, is a bright and showy body horror film about aging and the hypersexualization of the female body. But it doesn’t go much further than illustrating at great length that there are nasty cultural attitudes toward older women.

Body horror is particularly appealing to creators who would have previously found it difficult to make a living in the world of commercial film-making.
