I watched Attack the Block tonight and absolutely loved it. The trailer and the whole movie are apparently over at YouTube, so you can check it out. I recommend watching with the subtitles on, though, since that South London patois can be a bit hard to catch up with. I loved it that it all takes place in Wyndham Tower since the allusion is so stark and the population so blatantly non-Wyndham.
If that's not enough to keep you busy, I posted a whole bunch of links here.
