'Animal House' actress Mary Louise Weller dies at 79, a day before her 80th birthday

Hollywood paid tribute on 1 October 2026 to Mary Louise Weller, the American actress best remembered as sorority sweetheart Mandy Pepperidge in John Landis's 1978 fraternity-house comedy 'Animal House', who died after a brief illness one day short of her 80th birthday. Weller worked steadily through the 1970s and 1980s with roles in 'Forced Vengeance', 'Serial', 'Q: The Winged Serpent' and television series including 'The Rockford Files' and 'Fantasy Island', but 'Animal House' — one of the biggest-grossing comedies of its era and a formative film for a generation of American comedy — defined her legacy. Tributes from co-stars and classic-film fan accounts flooded social media, and Deadline, Legacy.com and other obituary trackers led their day's coverage with her passing. The near-miss of her 80th birthday added a poignant edge that made the story one of the most-read entertainment obituaries worldwide that day.
