Kane Parsons becomes youngest film-maker to open at No 1 in the US with Backrooms

Backrooms stunned industry observers by taking $81m in its first weekend, a record for studio A24

Kane Parsons has become the youngest film-maker to open a film at number one at the North American box office for his directing debut Backrooms.

Parsons, 20, is seven years younger than the previous record holder, Josh Trank, who was 27 when his debut Chronicle recorded a $22m opening in 2011. Backrooms stunned industry observers by taking $81m in its first weekend in North America - which was also a record for its studio, A24.
