I was pleasantly surprised when I discovered this and was instantly drawn into the world. For a few days after watching it, I kept thinking of that terrible boat and how paranoid and claustrophobic it was. Colin Farrell is great. Unrecognizable as an animalistic brute terrorizing first the streets of Hull, then the corridors and deck of a creaky whaling ship. But is everything as it seems? Jack O'Connell plays Patrick Sumner, a doctor with a past battling a morphine addiction. Impending doom looms as large and inevitable as morphine withdrawals.
