HOLLYWOOD, United States — Michael B Jordan on Sunday won the best actor Oscar for playing twins confronted with pure evil in vampire race fable “Sinners.”

He bested “Marty Supreme” star Timothee Chalamet, Leonardo DiCaprio of “One Battle After Another,” Wagner Moura (“The Secret Agent”) and Ethan Hawke (“Blue Moon”).

The Oscars kicked off on Sunday after months of expensive campaigns, with all eyes on the race between “One Battle After Another” and “Sinners” for best picture, Hollywood’s most coveted prize.

Tinseltown’s biggest stars were at the Dolby Theatre where host Conan O’Brien wasted no time in addressing one of the biggest talking points of the last few weeks– not conflict in the Middle East but controversy around Timothee Chalamet.

“Security is extremely tight tonight,” he told an audience who had walked through numerous checkpoints and a widened exclusion zone.

“I’m told there’s concerns about attacks from both the opera and ballet communities,” he said as the camera cut to Chalamet, a best actor nominee who caused a stir when he dismissed both art forms as things that “no one cares about.”

“They’re just mad you left out jazz,” quipped O’Brien.

Amy Madigan took home the first prize of the evening, winning the Oscar for best supporting actress for her turn as a demented witch in horror “Weapons.”

The veteran actress, who scooped the Actors Award two weeks ago, said she had known immediately that she wanted the role when she saw it.

“I love this script, and as soon as I read it, I knew I knew this woman,” she told journalists backstage.

“I was in the shower last night, and I thought, ‘Well, this must be a special day, because I’m shaving my legs’.”
