Danish actor Mads Mikkelsen has moved agilely between romantic leading-man roles (A Royal Affair) and blackhearted villainy (Casino Royale, TV’s Hannibal), with the occasional foray into comedy (Men & Chicken). As a downed pilot lost in a barren, treacherous region of Iceland, he carries this bone-chilling nature survival thriller with minimal spoken dialogue, his rugged physicality, and a wide spectrum of emotions. Early we see him shelter in the wreck of his plane, lay up provisions by ice fishing, and signal anyone who might be flying by; when a rescue chopper crashes, he breaks camp in an attempt to deliver the unconscious passenger (Maria Thelma Smáradóttir) to a lonely outpost mountains and miles away. First-time feature director Joe Penna and his cowriter and editor Ryan Morrison skillfully exploit genre conventions, but suspense arises mostly from what fresh hells they devise for the hero to conquer, for conquer he must.
