This prototypical _film noir_, which saw rookie director John Huston adapting Dashiell Hammett’s only Sam Spade detective novel, was the last movie I watched in 2010. Warner Home Video’s recently released Blu-ray version had been calling to me from the depths of my to-watch stack, and anyway it’s always been one of my favorite movies — immaculately designed, evocatively photographed, and easy to watch but also spiky, morally complex, and ultimately unsettling. Humphrey Bogart is so beloved a figure in American film history that it always catches me a little off-guard to realize that the superficially charming character he’s portraying here isn’t the dedicated moral crusader that convention might lead one to suspect. Arguably, he’s rather a glad-handing sociopath.
