Production designer Laurence Bennett: “We had this weird dichotomy where we had the ‘real world’ and films within the film,” he says. “We decided that, to whatever extent possible, the sets that were seen in the studio or seen entirely within film would be rendered in black and white, and the ‘real world’ scenes were done in naturalistic color.” By way of example, he cites the restaurant where George and Peppy dance together for the first time. “That set was done entirely in black and white—the wood grain, the paneling in the set, is entirely faux, and it was all done in black and white and gray,” he says. “It literally photographed differently. Secondly, that’s also for the cast and crew—I think that helped them get more into the period.” (Vanity Fair)
