High Sierra is a 1941 heist film and early film noir written by W.R. Burnett and John Huston from the novel by Burnett. The film features Ida Lupino and Humphrey Bogart and was directed by Raoul Walsh on location at Whitney Portal, halfway up Mount Whitney in the Sierra Nevada of California.
The screenplay was co-written by John Huston, Bogart's friend and drinking partner, adapted from the novel by William R. Burnett (also known for, among others, Little Caesar and Scarface). The film cemented a strong personal and professional connection between Bogart and Huston, and provided the breakthrough in Bogart's career, transforming him from supporting player to leading man.
The film contains extensive location shooting, especially in the climactic final scenes, as the authorities pursue Bogart's character, gangster "Mad Dog" Roy Earle, from Lone Pine up to the foot of the mountain.
