In the Heart of the Sea is a 2015 historical adventure drama film directed and co-produced by Ron Howard from a screenplay by Charles Leavitt and a story by Leavitt, Rick Jaffa, and Amanda Silver. An international co-production between the United States and Spain, the film stars Chris Hemsworth, Benjamin Walker, Cillian Murphy, Tom Holland, Ben Whishaw, and Brendan Gleeson. It is based on Nathaniel Philbrick's 2000 non-fiction book In the Heart of the Sea: The Tragedy of the Whaleship Essex, about the sinking of the American whaling ship Essex in 1820, an event that in part inspired Herman Melville's 1851 novel Moby-Dick.

The film premiered in New York City on December 7, 2015, and was released in cinemas in the United States on December 11, 2015, by Warner Bros. Pictures. In the Heart of the Sea received mixed reviews from critics and was a box office bomb, grossing only $94.3 million against a $100 million budget.
