A lot of films have already been mentioned that I would put on the list, a couple that I’d like to add
Frailty - Bill Paxton is a single father who is instructed by God to go out and kill people that God has told him are evil demons. His 2 sons are taken along to help. An interesting thriller.
The Apostle - Ok, not really a film with a theological plot as such, but an interesting story of a Southern preacher who goes off the rails a little. Played brilliantly by Robert Duvall.
