“Oppenheimer,” a solemn three-hour biopic that became an unlikely billion-dollar box-office sensation, was crowned best picture at the 96th Academy Awards that doubled as a coronation for Christopher Nolan.

From a quirky fairy tale romance to a dark comedy about a murder investigation, via a couple of coming-of-age tales and a horror satire, the contenders for the best picture Oscar offer audiences an array of genres and themes.
