As first announced on Production Intelligence on 29 October, Keepers is a period feature film gearing up to shoot in the UK next spring.

The film is set to star Gerard Butler, Peter Mullan and Joe Alwyn as three lighthouse keepers who arrive for their six-week shift.

But they soon come across something that isn”t theirs to keep and things take a sinister turn as a battle for survival is peppered with isolation and paranoia.

The story is inspired by the real-life events of 1900 which took place on a small island group just off the Outer Hebrides and which became known as the Flannan Isles mystery.

PI subscribers will have seen that the director is Kristoffer Nyholm, best known for The Killing and who recently helmed the first four episodes of Tom Hardy”s Taboo; this will be his first feature film.

The director said of the casting news: “I feel incredibly fortunate to have Gerard Butler, Peter Mullan and Joe Alwyn leading the cast of Keepers – great actors who are deeply committed to this project, and who will go the distance.

“These men are the strong and unique characters at the heart of this story, which is a journey from innocence to animalistic survival…”

The UK end of things will be produced by Andy Evans, Ade Shannon and Sean Marley of Mad as Birds, a production company with offices in York and Wales. He is joined by Butler and Alan Siegel for G-BASE and Brian Oliver for Cross Creek Pictures.

Renowned casting director Reg Poerscout-Edgerton wears the co-producer”s hat for this one, as well as being on casting duties.

PI subscribers should follow the project as we will be updating as more HoDs board and dates are locked down.
