Demonoid

Erika Carlsson played the nurse as well as the topless possessed woman at the beginning of the film, even though she was only credited as Nurse Morgan. She holds the rare distinction of being killed twice as different characters in a single movie.

In the first scene, the hand supposedly chopped off that woman is way too big to have been that woman's hand.

A comparison between the US version and the Mexican version shows that both contain different footage. The face-crusher death scenes are more violent on the Media Home Entertainment version. The Mexican version has an alternate soundtrack, extended dialog scenes, cut scenes, alternate death scenes, and a slightly different ending. However, it is missing the first three minutes of the satanic cult chopping the girl's hand off.
