The Crazies (2010) 
The modern remake of Romero's political 70's horror about biological weapons. This new version diverts a bit from the original story, pretty much only keeping the premise of the water being being polluted by 'codename Trixie'. There are some fabulously tense set pieces including one involving an automatic car wash. A good start to the marathon, £1.50 in CEX well spent!
