All aboard the Charlie Hunnam train! Next stop: the Amazon . Mystery and intrigue await.

In The Lost City of Z , Hunnam plays British explorer Percy Fawcett, who disappeared in 1925 while surveying evidence of an uncharted jungle that he said once housed an advanced civilization. The Huffington Post has an exclusive clip from the movie, written and directed by James Grey (We Own the Night, The Immigrant), in which Fawcett attempts to make peace with a tribe during his expedition.

The Lost City of Z opens April 14. It also stars Sienna Miller, Robert Pattinson, Tom Holland and Ian McDiarmid.
