Brendan Fraser won the best actor Oscar for “The Whale,” a transformative role in which he revived a career that was once so bright. Fraser was one of five first-time nominees in the category, the first time that had happened since 1935. Fraser beat out Austin Butler of “Elvis,” Colin Farrell of “The Banshees of Inisherin,” Paul Mescal of “Aftersun,” and Bill Nighy of “Living.”
