This episode covers the little known "The Prophecy" franchise. It's a five film series about a millennia-long war among angels. The first three movies star Christopher Walken. The last two were filmed back to back in Romania (and are really the same story). 

The first film was released theatrically in 1995 and has since become a cult classic. The other four were direct to video and have, for the most part, fallen out of the public conscience. 

If you like angel movies (such as "Legion", "Fallen", "Constantine", "Angel Heart" or "Warlock") give these a try. I would suggest the first (and possibly second) movies. The rest are not horrible but dont add much to the mythology.
