The first trailer for new vampire thriller The Radleys, starring Line of Duty’s Kelly Macdonald, has been released.

Adapted from Matt Haig’s novel of the same name, the film centres around a married couple who are hiding a dark secret from their children: they’re vampires.

The film will receive its world premiere at the upcoming Edinburgh International Film Festival on Tuesday, August 20. Sky has also confirmed The Radleys will then be released on Sky Cinema and in cinemas on October 18.

“The Radleys are an ordinary family who hold a dark secret… they are abstaining vampires,” reads the official synopsis for the film.

“As if being a teenager wasn’t bad enough, bloodthirsty instincts take over the teens of the family, revealing the terrifying truth and opening the door for an extended family member to re-enter and upend The Radleys’ once perfect slice of suburbia.”
