 The script originally featured an actual Bloody Mary who, when  summoned by the mirror game, rose from the depths of the lake to  murder the characters one by one. Director Robert Wilson decided  that it would be more interesting if the evil force was never seen,  but instead could manifest itself in any one of the old friends  gathered at the cabin, thus making the film more a creepy paranoia  piece and less a supernatural slasher film. However, many film  websites still make reference to the films original (and now  incorrect) synopsis.
