Radius has released the trailer for the Austrian horror film GOODNIGHT MOMMY that premiered at the Venice Film Festival and the internet is calling the film “the scariest of all time.” Directed by Veronika Franz and Severin Fiala, the film is about nine-year-old twin brothers who are waiting for their mother. When she comes home, bandaged after cosmetic surgery, nothing is like before. The children start to doubt that this woman is actually their mother. It emerges an existential struggle for identity and fundamental trust.

GOODNIGHT MOMMY is set for release in the US on September 11th.
