Movie fans may recall the 1980s controversy surrounding the colorization of black-and-white movies. When Ted Turner purchased the film inventories of MGM, Warner Brothers, and RKO, the media mogul was intent on draping color onto chiaroscuro. The idea of “King Kong” (1933) and “Casablanca” (1942) festooned with rainbow palettes raised hackles. Mr. Turner didn’t flinch: “The last time I checked, I owned the films … I can do whatever I want with them.”
