Milly Alcock and Toni Collette Trapped in Deadly Sauna in Upcoming Psychological Horror Film

In the coming years, Milly Alcock may be suiting up as the next Supergirl in the new DC Universe, but her next project is a far cry from the world of superheroes. The House of the Dragon breakout star is set to lead a psychological survival thriller called "Hot Mother," co-starring horror genre icon Toni Collette.

The film, the debut feature from Australian writer-director Lucy Knox, follows a mother and daughter who check into a remote wellness retreat, only to find themselves trapped inside a sauna with no way out and no one to hear them scream. What ensues is a tense, physically brutal fight for survival that blends psychological horror and raw endurance.
