When it was announced a couple of months ago that Cary Fukunaga would no longer be directing a new adaptation of Stephen King’s It, it seemed like we would have to wait a fair bit longer to see what he would do to follow up his acclaimed run on the first season of True Detective. But over the past year or so, he has been quietly working on a new movie for Netflix called Beasts of No Nation and this week the first trailer has arrived online. The movie stars Idris Elba as the leader of a brutal guerilla group in West Africa that takes young children and turns them into soldiers. Based on the novel by Uzodinma Iweala, it looks to be an intense and emotional experience that draws from the grim realities of life in certain parts of Africa. Beasts of No Nation debuts in select theatres and on Netflix on Oct. 16th; check out the trailer after the jump and see what you think.
