King Arthur in Hollywood

Jean Delannoy's (screenplay by Jean Cocteau) "The Eternal Return", 1943. Though a WWII era modernization incorporating racial overtones among other things, it remains in other areas very true to the legends. It's a retelling in modern terms of the Tristan and Isolde story. Patrice (played by the great Jean Marais) goes in search for a wife for his uncle and finds Nathalie (Madeline Sologne). They fall in love, and as in Tristan the love sealed with a love potion, but she marries the uncle anyway. Unable to live without each other, they run away together and spend a short but blissful time in a cozy hut in a snow-covered landscape, all beautifully and sensually photographed. The uncle eventually finds them and brings Nathalie home with him. Patrice meets an old friend and his sister, whose name just  happens to be Nathalie, too. They fall in love and plan to marry, but he can't get the other Nathalie out of his mind. Determined to see her one last time, he is wounded. Sying, he sends his friend to bring her to him, but is deceived by the second Nathalie, the plot using white and red scarves rather than the color of the sail.
