"These portrayals in these movies tend towards sensationalism," said Rev. Mark Morozowich, dean of theology and religious studies at the Catholic University of America. "It creates a hysteria among some people and it creates fantasies among other people. I think this has caused undue fascination with these things."
Morozowich said in some cases exorcisms are legitimately necessary and solemn tasks taken on by a priest.
"While possessions do exist, they are meant to be something more private," Morozowich said. "Sometimes it trivializes that experience by fantasizing it."
