yes and bogart performance be classic and and peter lorre and sydney greenstreet be terrific they usually be . but the film suffers from the production code of the day while hammett novel hold up and and the sexual politics of it wasn not allow to be transfer to the screen ( although it could have with good write casablanca have a lot of dark sex joke ) . the big problem with the film be mary astor . i do not find her attractive and her performance be mannered and oft put which be a disaster for a femme fatale . in the novel and the character come across a much prettier and smarter and and the sexual relationship with spade make her much more devious while it also make the love talk at the end and spade rejection of brigid logical . in the film and when this conversation start and one be leave wonder and what . these two have barely be on screen together and now there talk of true love . one part near the end illustrate the problem with the story a filmed represent in the book and when gutman claim a thousand dollar bill be miss and spade make brigid get naked in the bathroom a he inspect her and her clothes to see if she take it . brigid protest and but be not modest and and gutman be surprise that spade would do this . this scene reinforce spade cold demeanor and the sexual relationship between brigid and spade and and impress gutman with spade icy thoroughness . a filmed and brigid just make a silent and know nod of no and and that that . the hayes code eradicate a key scene and and the writing do not attempt to find a way to make up for this loss . if brigid have be play by a smarter and more seductive actress and the sexual relationship between her and spade be allude to and then the dark motivation of the story and spade character would be fully realize . a it be and it a well cast movie ( but nearly destroy by one casting flub and astor ) and influential in term of character and pace and and camera choice . it may have be the first noir and but that alone doesn not make it a classic . a it be and watch it be more history than enjoyment and while the novel still hold up as well write detective fiction .
