Olivia Wilde’s “Don’t Worry, Darling” is — on its immaculately, obsessively polished surface — a film about the danger of dreams. Even if you have somehow avoided all publicity for the film, the pop culture reference points should already be clear. Pugh conveys blissful serenity and anguished confusion with equal conviction; her deftness justifies Wilde’s poetic anti-narrative, and vice versa. The real world feels like ghostly and desaturated reflection. “Don’t Worry, Darling” is a movie that airily warns you to watch out for illusions even as it revels in a film’s power to create a world deliberately untethered from reality.
