John Boyega is famous today after his Star Wars work, but this was the film that kicked off his career when he was a complete unknown.
Attack The Block (2011)
In which he is the teenage thug who becomes a hero by saving his council estate from an invasion of low budget aliens made of black polyester fur. A silly story that is gigantic fun, wonderful entertainment. This is the man who is so talented he single handedly made Pacific Rim into something worth watching. And sexy as fuck along with it.
