The most important movie filmed in and around Lone Pine is director Raoul Walsh's "High Sierra" (1941), starring Humphrey Bogart as Roy Earle in the role that moved Bogart from respected supporting player to leading man. Cast and crew lodged in Lone Pine, and Walsh shot various scenes in and around Lone Pine. For the film's mountain chase scenes, Walsh took everyone to nearby Mt. Whitney, where pack mules lugged camera equipment up the mountainside: "filming began just outside Lone Pine ... on August 5, 1940. ... On a slope at the side of Mt. Whitney, ... a group of twenty men from the studio worked for four days to clear a path so that mountain-trained mules, packing cameras and other equipment, could get up to the shooting area. ... Bogart had to run three miles up a mountainside for two days ... Walsh ordered all the big boulders removed from the path of [Bogart's] final fall, but the little ones remained, and Bogart complained about that plenty ... Bogie especially did not want to trek up that mountain. This was the shoot on which Walsh gave him the nickname 'Bogey the Beefer'". John Huston wrote the screenplay, and Ida Lupino co-starred.
