For a split of a second at the end before the credits roll there are the coordinates shown for the Riverview Hospital, which are "49 14 122 48".
At the end of the credits, a message reads: "No Rats Were Eaten During The Making of this Film".
After the credits roll, there is a short scene with Tessa and Jennifer in the dorm room discussing the events of the party.
The standard paragraph at the end of most credits stating that the movie is fictitious is altered to say: The Events, Characters, and images depicted in this photoplay are fictitious. Any similarity to actual persons, living or (un)dead, or to actual events is purely coincidental.
