“Nope,” which recently crossed the $100 million threshold at the domestic box office, is the “Get Out” filmmaker’s self-described “great American UFO story.” “Nope” is just as thoughtful and provocative as Peele’s earlier movies (“Get Out” and “Us”), but much grander in scope and more technically complex – it’s a big movie, largely filmed in IMAX, that absolutely envelops you.“Nope” follows a pair of siblings (played by Daniel Kaluuya and Keke Palmer), who inherit their father’s horse ranch following his mysterious death. (He was struck by falling debris from something.) They come from a long line of horse trainers/stunt performers and are desperate to keep the business afloat.
