Los Angeles | Paul Thomas Anderson's "One Battle After Another" was crowned best picture at the 98th Academy Awards, handing Hollywood's top honour to a comic, multi-generational American saga of political resistance.

The ceremony Sunday, which also saw Michael B. Jordan win best actor and "Sinners" cinematographer Autumn Durald Arkapaw make Oscar history as the first female director of photography to win the award, was a long-in-coming coronation for Anderson, a San Fernando Valley native who made his first short at age 18 and has been one of America's most lionised filmmakers for decades.

Before Sunday, Anderson had never won an Oscar.

The Oscar night belonged to Warner Bros, the studio of "One Battle After Another" and Ryan Coogler's vampire tale "Sinners". It was an oddly poignant note of triumph for the fabled studio, which weeks earlier agreed to a sale to Paramount Skydance, David Ellison's rapidly assembled media monolith. The deal, which awaits regulatory approval, has Hollywood bracing for more layoffs.

"Sinners" and "One Battle After Another" were each Hollywood anomalies: big-budget originals born from a personal vision. In a year where anxiety over studio contraction and the rise of artificial intelligence often consumed the industry, both films gave Hollywood fresh hope.
