Hollywood star Gerard Butler was back in Scotland in Dumfries and Galloway to film his latest movie, Keepers.

The thriller is about the disappearance of three lighthouse keepers.

It will cast a dramatic new spin on the 1900 mystery, when keepers Thomas Marshall, James Ducat and Donald MacArthur vanished from the lighthouse in parlous weather.

Glasgow Times:

No sign of struggle was found in the lighthouse: only an overturned chair and one set of unusued oilskins was found, suggesting one of the keepers had left without them - but the beds were unmade, the clocks stropped, the lamps clean and refilled, with the island itself severely damaged by storms.

The mystery, in which the bodies of the men were never found, inspired a Doctor Who episode Horror of Fang Rock, a Genesis song, Wilfrid Wilson Gibson's ballad Flannan Isle and The Lighthouse, an opera by the late Sir Peter Maxwell Davies.

The movie is also starring Scots actor Peter Mullan and Connor Swindells.
