The Trail of the Lonesome Pine is a Technicolor 1936 American romance film based on the novel of the same name. The picture was directed by Henry Hathaway starring Fred MacMurray, Sylvia Sidney, and Henry Fonda. It was the second full-length feature film to be shot in three-strip Technicolor and the first in color to be shot outdoors, with the approval of the Technicolor Corporation. Much of it was shot at Big Bear Lake in southern California. The Trail of the Lonesome Pine was the fourth feature film adaptation of John Fox Jr.'s 1908 novel, including 1916 and 1923 silent versions. As with the novel, the film makes extensive use of Appalachian English in the dialogue.
