A surprising amout of alien-invasion movies are due out in 2011, but save for one of them, they're all Hollywood flicks that can afford to put themselves on your radar by buying a Super Bowl ad. The exception? 'Attack the Block,' the directorial debut of Joe Cornish ('The Adam and Joe Show'), which just had its trailer premiere over at Empire (embedded below).

From the producers of 'Shaun of the Dead,' 'Attack the Block' looks like the anti-alien-invasion blockbuster. It doesn't involve soldiers fighting off spaceships. It doesn't involve conspiracy theories on the moon. It doesn't involve entire cities being destroyed. It's about a gang of teens who must protect their neighborhood from space invaders. Think of it as the 'Monster Squad,' just with, ya know, aliens.

Unfortunately, as of right now 'Attack the Block' doesn't have U.S. distribution, but hopefully that will change after its world premiere at the SXSW Film Festival in a little over a week.
