The Crazies (1973) (DVD)

Its code name is 'Trixie', an experimental government germ weapon that leaves its victims either dead or irreversibly insane. When the virus is accidentally unleashed in Evans City, Pennsylvania, the small community becomes a war zone of panicked military, desperate scientists and gentle neighbours turned homicidal maniacs. Now a small group of citizens has fled to the town's outskirts where they must hide from trigger-happy soldiers while battling their own depraved urges. But even if they can escape the madness of this plague, can they survive the unstoppable violence of The Crazies?
Richard France (Dawn Of The Dead), Lynn Lowry (Shivers, Cat People) and Richard Liberty (Day Of The Dead) co-star in this little-seen masterpiece of modern horror written and directed by George A. Romero that remains one of his most chilling and disturbing films ever.
