The other day I sat down to watch a 1947 movie called “Sinbad, the Sailor” and was not quite prepared for what I saw when I clicked “play”: it was the usual “An RKO Radio Picture” logo—but in Technicolor! I can’t imagine “Sinbad” is the only movie to feature the logo in color but it’s the first one I remember seeing. And look how magnificent it was in color. The movie itself was only okay. Douglas Fairbanks Jr. did a retreat of his father in “The Thief of Bagdad” (1924) and Maureen O’Hara stood around looking more stunning than she ever had before. The real star of the picture were the sets and costumes. The crew used every possible hue available to them and shot it all in glorious, glowing, gorgeous Technicolor.
