I'm all for genre-mixing - not everyone's on a hot date or exploring a savage island when the zombies invade. This French "gangsters vs police vs zombies" film called "La Horde" looks like a great example.
There are scenes in the trailer that remind me of several survival horror games - all the way from the original Resident Evil up to Left 4 Dead. I think this is a good thing, as it may add a few scares via sense memory for the gamers out there.
"La Horde" is premiering at the Film 4 Frightfest in London - let's hope we get a subtitled version on these shores!
