The Exorcism of Emily Rose is a 2005 American supernatural horror legal drama film directed by Scott Derrickson and starring Laura Linney and Tom Wilkinson. The film is loosely based on the book The Exorcism of Anneliese Michel by Felicitas D. Goodman, which tells the story of Anneliese Michel and follows a self-proclaimed agnostic (Linney) who acts as defense counsel representing a parish priest (Wilkinson), accused by the state of negligent homicide after he performed an exorcism.

Felicitas D. Goodman was an American linguist and anthropologist. She was a highly regarded expert in linguistics and anthropology and researched and explored Ecstatic Trance Postures for many years. She studied the phenomenon of "speaking in tongues" in Pentecostal congregations in Mexico. She is the author of such well-received books as Speaking in Tongues and Where the Spirits Ride the Wind: Trance Journeys and Other Ecstatic Experiences. Her work has been published mostly in the United States and Germany.
