A Aldeia dos Amaldiçoados

The eerie effect of the children's glowing eyes was created by matting a negative (reversed) image of their eyes over the pupils when they used their powers. The British print of the film contained no optical effects, as the British Board of Film Classification considered them too frighting for an 'A' classification.

An abdominal X-ray is displayed which supposedly shows the fetus of a pregnant woman. Not only is there no fetus, the X-ray isn't even that of a woman, as the pelvis is obviously that of a man.

In order to get an 'A' certificate in the UK no optical effects shots were used in the UK print and original footage or alternative shots used instead. Both the UK and the 'standard' version of the film run to the same length. At the end of the film no glowing eyes are seen rising from the flames in the UK version, which also has a "Made at M.G.M British Studios, Borehamwood, England" credit. Because this change was requested at the scripting stage there is no reason to believe that the two versions of the film were not edited in tandem. It is incorrectly stated that the British print has the burning man sequence cut. This was a cut requested by the Production Code office in the US and is the same for both versions of the film, where the victim is never engulfed by the flames in close-up, which contradicts the long shot seen in the sequence.
