Amy Madigan wins Oscar as 'Weapons' villain Aunt Gladys

But her fan-favorite turn as the voodoo-wielding evil Aunt Gladys in horror hit "Weapons" has made her a TikTok star -- and an Oscar winner for best supporting actress. The 75-year-old Madigan on Sunday bested a crowded field that included Teyana Taylor ("One Battle After Another"), Wunmi Mosaku ("Sinners"), and two stars of "Sentimental Value" -- Elle Fanning and Inga Ibsdotter Lilleaas. She also defeated a long-standing tendency for horror films to be ignored when it comes time to hand out the golden statuettes.
