The Vanishing

Four different lighthouses were used to create what is seen in the movie as a singular location: Mull of Galloway lighthouse was used for exterior and interior cottages, lighthouse, lighthouse garden and the headland of the island. Killantrigan lighthouse was used for its interior staircase and side garden. Corsewall lighthouse was used for a single interior shot and to create the cliff for many of the cliff scenes. Cloch lighthouse was used for the interior lightroom as it is no longer operational, yet beautifully preserved.

At the time of the mysterious disappearance the lighthouse was not equipped with radio, in fact radio-telephone technology was not available in 1900 at all.

Radio had been invented and demonstrated just a few years earlier, however, commercial radios were not available at this time.
