Before you go asking, no, this isn't a film about the necklace that Old Rose throws into the ocean at the end of Titanic (although, James Cameron, if you're stuck for ideas...), but is Ron Howard's latest adventure based on Nathaniel Philbrick’s best-selling book about the dramatic true journey of the Essex, a Nantucket whaling ship that was destroyed by a sperm whale in 1820.
In the Heart of the Sea is basically the story of the story that inspired Moby Dick, and stars Hemsworth as first mate Owen Chase who's forced to take command after the disastrous encounter and deal with the decisions that the crew have to make to survive on the high seas.
Apparently the cast, including Benjamin Walker, Cillian Murphy, Ben Whishaw, Tom Holland, Brendan Gleeson and Jordi Molla, suffered from seasickness while filming as well as having to deal with restricted diets they'd been put on to them that good old fashioned starving to death look, so between that and Howard's history of ruining environments for moviegoers (see Apollo 13), this will probably make you never want to go on a boat again. Ron Howard certainly doesn't do movies by halves.
In the Heart of the Sea is expected in cinemas in March 2015.
