Speculation here, some of NYC trads. believe that "Bones" was Malachi and that the exorcism brought about his conversion. Ideally many N.O. 60s priest could have fit the bill.
Trying to jog my memory on past conversations of friends who knew him regarding exorcisms... oh well, perhaps Fr. Jim or Unknown can weigh in.
By the way, is it me or was that music awful?
Can't help wondering what is the back story behind this group producing the film?
