Margaret O’Brien – 84 Years Old

Being four years old didn’t stop Margaret O’Brien from acting, and at that age, she already had a contract with MGM. She quickly gained popularity after appearing on Babes on Broadway and Journey For Margaret, but it was her role on Meet Me In St. Louis, opposite Judy Garland, that made her an absolute child star. She then won a Juvenile Academy Award, which was unfortunately stolen by her maid. O’Brien miraculously found it after 50 years of searching. Though many would have thought that her retirement would have come decades ago, O’Brien is still active. In fact, in 2018, she did a film called Impact Event.
