The film was originally shot in Italian and dubbed in English, with some shots redone with the American actors speaking English. The release in the United States is this version, with some actors speaking English on camera, but with an English dubbed soundtrack. This has the odd result of some actors, like Jared Martin speaking English on camera, but still obviously dubbed by another voice actor.
Filmed in November, 1986.
On some of the dorm room walls at the Institute there are posters of Rocky Balboa, and Maverick from Top Gun (1986).
This film's plot is oddly similar to an episode of the TV series Smallville. In the episode titled "Spirit", a popular teen is comatose after a car accident and possesses everyone she comes in contact with. In this film, the comatose teen is unpopular and exacts her revenge on her tormentors while also possessing just one other person rather than several people.
