Scary Movie 2 (2001)

Megan Voorhees is possessed, and two Priests, Father McFeely and Father Harris, must drive the demon out, but the exorcism doesn't go as planned. A year later, survivors Cindy Campbell, Ray Wilkins, Shorty, and Brenda Meeks, are at college, trying to forget the incidents that occurred last Halloween. Professor Oldman and his assistant, Dwight, have decided to do a research study at Hell House, the house where the bad exorcism took place, and disguise it as a sleep disorder study. Chaos starts as soon as Cindy arrives and meets creepy caretaker Hanson. But the group has secrets to solve, even if they are scary or disgusting.
