Thor himself, Chris Hemsworth stars in this historical survival tale directed by Ron Howard. The story is based on the true account of the Essex, a ship that was sunk by a gigantic whale in 1820 and served as the inspiration for Herman Melville's Moby Dick. Howard creates some evocative images of early 19th century New England. And the film's 3D special effects viscerally capture life aboard a whaling ship. The subject matter—the brutal, archaic whaling industry—might not be everyone's cup of tea, however. 121 minutes PG-13.
