Before I say anything else, let me warn you that this video contains scary and disturbing scenes from the films The Rite and The Exorcist. If you have young children around, please do not click on this video.
Having said that, this video is a segment from CNN, featuring Fr. Gary Thomas. Fr. Thomas is an exorcist whose life story served as the basis for the movie The Rite. It's a good interview, and it was good to see a sober, non-sensationalized account of exorcism in the mainstream media.
(I found this video via the Catholic Trailers blog.)
