In an Academy Awards ceremony where an onstage altercation between Will Smith and Chris Rock overshadowed the honors, “CODA” from Apple TV+ won the Oscar for best picture, becoming the first film from a streaming service to be welcomed into that rarefied Hollywood club. The 94th Academy Awards on Sunday had a freewheeling, irreverent tone from their start, with ABC and the Academy of Motion Picture Arts and Sciences laboring to prove that the Oscars could be lively and culturally relevant. By the ceremony’s end, it was certainly a night for the Hollywood ages.
