Just saw the latest film from the crew of "Shaun o.t.Dead", which has an alien-invasion stopped by a suburban, london teenage-gang.
The main-acteur looks like a 15 year old version of denzel wahington (in a good way, he has charisma) and another good thing the film has - Mike Frost (although he doesnt show up to often, but its still cool)!
If you want a totally different approach to the topic; check it out, its a good one. (Love the brits for their movies, always original)
