The Lost Weekend (1945) by Billy Wilder, and starring Ray Milland as writer Don Birnam, and starring alcohol as itself, perfectly in character as a marvellous and demonic fixe-fatale, is a low-key and visionary tale of alcoholic failure, and as such uniquely emotional and modern, for the 1940s.
The Lost Weekend is also a landmark in film noir and a high station in Hollywood history, being among other things the winner of a Best Picture Oscar . . . in fact The Best Picture Oscar, in fact, and there may be little more significant when assessing the history of one style, genre or cinema
This Best Picture Oscar was a deserved win for many reasons, and that included morality which always plays a part in this decision, each year, no matter what the style of picture.
It was a deserved win for the modernity and humanity of The Lost Weekend, which is a film that does not dazzle so much as invite the viewer on a slow and focused ride to the bottom. There is no complexity other than in the acting, and even the script does not veer, even when it surprises with its hidden bottles of rye and constant feeling of domestic and internal desperation.
The Lost Weekend is still a film noir however. Even though there is no murder, there is above all else a psychological horror which in cinematic terms could only find its feet in film noir in the 1940s.
