For our money, Leonardo DiCaprio should have won an Oscar for his performance in Shutter Island. Playing an unhinged US Marshal who's sent to a reclusive island to track an escaped prisoner, he soon discovers there's a lot more going on on the island than the warden (Ben Kingsley) and his partner (Max Von Sydow) are letting on. A dark, twisted, gothic melodrama from Martin Scorsese, this comes highly recommended.
