The DVD, released in the US and Canada by Disinformation, contains the full 80 minutes version of the documentary, in depth interviews with two of the most prominent exorcists of the Chatolic Church, Fr. Fortea and Fr. Gabriele Amorth in addition to a long sequence of the exorcism ritual from the film.
Here is a quote from a viewer:
“I caught this at Fantastic Fest in Austin and let me tell you, despite this film being nominally a documentary, the real life exorcism of a Colombian woman is captivating, disturbing and really makes you think there might be something to exorcisms, even if you don’t really believe in religion.”
