I happen to love black-and-white for its own silver-toned luminosity, but every so often you say to yourself “good as it looks, this monochrome film would have been fascinating in color.”
Howard Hawks‘ Red River is at the top of this list. I would have dearly loved to see Billy Wilder‘s Sunset Boulevard in Techniolor…how could it have been hurt by that? And speaking of Hawks, Only Angels Have Wings and Bringing Up Baby would have been glorious in color. Which others?
