Over 100 years ago, Captain James Harvey and the crew of The Hesperus docked at the island of Eilean Mor, off the coast of northwest Scotland. Their job was simple: relieve the 3-man crew manning the island’s lighthouse. What they found, or rather what they didn’t find, has inspired Keepers, a new feature film starring Gerard Butler and debuting at this year’s Cannes Film Festival.

Known as the Flannan Isle mystery, the tale of these three lost men remains an unsolved mystery to this day. Theories for their tragic disappearance range from a rogue wave to murder and the paranormal. Scottish historians say the small island has always had an air of superstition surrounding it, with locals telling of a lone chapel that inspired dark reverence and demanded rituals from island inhabitants and visitors alike. The tale even spawned an eerie 1912 Scottish ballad.

Scotsman Gerard Butler (300, RocknRolla) returned to his homeland for the film, which shot in The Mull of Galloway, the southernmost point of Scotland where a 200-year old lighthouse still shines. Butler will star with fellow Scotsman, Peter Mullan (Warhorse, Trainspotting) and Connor Swindells, who is making his feature-film debut. Keepers is produced by Mad Dog Films and Cross Creek Pictures.

A release date for Keepers is forthcoming. Until then, we suggest you keep a light on.

On an uninhabited island 20 miles from the rugged Scottish coast, three lighthouse keepers arrive for their 6 week shift. As they settle into their normal quiet routine, something unexpected and potentially life-changing occurs. What follows is a tense battle for survival, fed by isolation, paranoia and greed, leading three honest men down a path to destruction.
