The surprising transformation is for his upcoming film, In The Heart of the Sea, a dramatization of the true story that inspired Herman Melville's Moby Dick. Hemsworth plays the shipwrecked captain who fights with an enormous sperm whale and leads his surviving crew against all odds against the uncaring hostility of nature itself. There may also be some cannibalism involved.

In the Heart of the Sea opens on December 11th.
