Recipe for Priest.
Take 2 large portions of The Searchers, a fat slice of Bladerunner, Chuck them in a pan with a good dollop of cheese. Chuck in a handful of Judge Dredd, a pinch of 1984 with a good dash of Mad Max, a sprinke of Dark City and keep it on a low simmer, don't worry, it won't get to boiling. At this point, you might want to add some cuts from Alien. Don't.
Work in a few crushed best lines from classic movies, a soupcon of Pitch Black for mood, and stir in the effects from I am Legend. and there you have it!
