Much of the filming was carried out in the abandoned village of Tyneham in Dorset. The residents were forced to move away in 1943 "as a temporary measure" because the War Office (now the M.O.D.) commandeered the village to use it as firing ranges for training troops. After the war, the Army placed a compulsory purchase order on the land and it has remained in use for military training ever since. However, the remains of the buildings in the village are sometimes open to the public, despite being in the middle of a firing range. The village's very rare 1929 K1 Mark 236 telephone kiosk, which had been restored by volunteers a few years earlier, was accidentally flattened during filming of this movie, and the movie company had to obtain a replacement.

The action is set in the 1830s, but the Lanternist's magic lantern dates from the 1860s.

At the end of the film, information about what happened to the six Martyrs appears onscreen in the style of a magic-lantern show.

To receive a PG certificate a 3 second cut was made to UK cinema and video versions during a scene hinting at oral sex between McCallum and his dog. The cut was waived for the 15-rated BFI DVD release in 2009.
