So many zombie films out there atm, the genre is new again and from a film-making point of view it is so much fun.
Of all the short films I have worked on horror is the best for the crew and zombies for some reason keep the set really upbeat, everyone has a blast.
Seems like every 2nd indie filmaker is doing one now, dead snow and the horde come to mind straight away from semi- recent releases. REC would prob be my fav from the indies, it's pretty innovative and scary as hell.
