According to Sandra Bullock in the DVD commentary, while filming the scene where the Owens women are drunk and slinging insults, the actresses actually got drunk on very bad tequila brought by Kidman. The cast further stated in the film's commentary that they felt supernatural elements of the house started to affect them. Both the cast and crew claimed they heard supernatural noises while filming the coven scene at the end of the film. For the final scene with all of the townspeople at the Owens home, the entire population of the town where filming took place was invited to show up in costume and appear as townsfolk.
