Aka Keepers. In 1900, three lighthouse keepers, James (Gerard Butler), Thomas (Peter Mullan) and the newcomer Donald (Connor Swindells) depart for their six-week long sojourn at the remote Flannan Isles lighthouse. After a storm, they find a boat with an apparently dead man who’s been flung out of it. But when Donald tries to winch up a heavy trunk that’s fallen out, the man rises out of the water and tries to kill the youngster – before he defends himself. Thomas is the first one to open the trunk and finds it filled with gold ingots. Then the dead man’s friends Locke (Søren Malling) and Boor (Ólafur Darri Ólafsson) turn up … Written by Joe Bone and Celyn Jones, and adapted from a true-ish story of the disappearance of three men from Eilean Mor Lighthouse, this admirably dour outing has a surprisingly effective psychological mechanism, one that was used to similar effect by John Huston decades earlier in Treasure of the Sierra Madre, itself a masterpiece of greed, guilt and amoral behaviour. It has that and old-school brutal violence going for it in a narrative stripped to the bone. The landscape may be different but the murderousness is of a highly vicious quality. Shot around the Mull of Galloway, Port Logan harbour, Killantringan Lighthouse near Portpatrick and Corsewall Lighthouse near Stranraer. Directed by Kristoffer Nyholm.
