Attack the Block

Joe Cornish directorial debut is Attack the Block and looks like it will be the hottest British film since Fuzz. With Nick Frost and producer of Scott Pilgrim Vs the World, Spaced and Hot Fuzz, Nira Park (Edgar Wrights Producer in all of his projects) This film should prove to be a true brit classic. here is the pitch and treatment from Twitch Film

Attack The Block is a fast, funny, frightening action adventure movie that pits a teen gang against an invasion of savage alien monsters. It turns a housing estate into a SCI-FI PLAYGROUND. A tower block into a fortress under siege. And weapon wielding teenage thugs into heroes. Think ASSAULT ON PRECINCT 13 only with monsters and a tower block. Or LA HAINE crossed with ALIENS. It's inner city versus outer space.

Trainee nurse Sam is walking home to her flat in a scary South London tower block when she's robbed by a gang of masked, hooded youths. She's saved when the gang are distracted by a bright meteorite, which falls from the sky and hits a nearby parked car. Sam flees, just before the gang are attacked by a small alien creature that leaps from the wreckage. The gang chase the creature and kill it, dragging its ghoulish carcass to the top of the block, with they treat as their territory.

While Sam and the police hunt for the gang, a second wave of meteors fall. Confident of victory against such feeble invaders, the gang grab weapons, mount bikes and mopeds, and set out to defend their turf. But this time the creatures are bigger. Much bigger. Savage, shadowy and bestial, they are hunting their fallen comrade and nothing will stand in their way. THE ESTATE IS ABOUT TO BECOME A BATTLEGROUND. And the bunch of no-hope kids who just attacked Sam are about to become her, and the block's, only hope.
