Although High Sierra (1941) is likely perceived by the public as a ‘Humphrey Bogart’ picture, it is not entirely fair to see it that way.
Indeed, High Sierra is notable in many ways for how Ida Lupino’s character develops, and how she is portrayed.
Viewers will also note that Ida has top billing too, before Bogart, and that is worth something!
Critically,
Ida Lupino plays a fairly ‘straight’ role here, and hers is not a character the readily fits into the various tropes and stereotypes which it is often said, dominate the female portrayals in the style.
By ‘straight role’ we can confidently say the following of Ida Lupino in High Sierra ― her character is consistent and develops across the course of the action.
While not cast as a femme fatale, or domestic simp of some sort, Ida's character, Marie, falls in love with Humphrey Bogart’s character, Roy, and remains true to the end. The entire episode is presented as her story, and her journey, with the viewer experience being hers.
Conversely, Bogart’s character is typical of a certain type of male from this era of film noir ― he may try to be doing good, but fate and his lower nature are in fact in control.
This means Roy Earle (Bogart) regularly makes wrong decisions, and not just when he is railroaded into them.
