The actors are well cast and their faces fit well into the time period. Chris Hemsworth looks very much like a 19th Century sea man if a bit larger than life as the first mate. Benjamin Walker has a face that looks very much like a 19th Century portrait of a New England man.
Last year Angelina Jolie's stranded at sea survival story "Unbreakable" gave us a taste of the thirst and horror of being without water. But this movie shows us more than thirst with cannibalism.
If like me you thought Moby Dick was boring, this movie is actually much more interesting. Worth watching on the big screen.
