Out now. Trailer here:-http://www.youtube.com/watch?v=K5Ysxp3MXek
Here's the description I got from my local Odeon:-In atmospheric British thriller ‘Tower Block’, a killer is picking off the remaining residents in a high-rise building on the verge of demolition.
Nobody can hear the shots and nobody is coming to help…but the occupants know that the reason they are being hunted is the murder they witnessed a year previously. But can they escape the silent killer who is stalking them on the lonely landings?
Sounds slightly more interesting than the trailer looks, and made me think of "High Plains Drifter" relocated to a tower block.
