Most actors spend years in small parts before the Academy notices them. A few skipped that stage. They stepped onto a film set for the first time in a major role and left the ceremony with a statuette.
These six winners came from very different places, including the stage, a pop singing competition, a drama school, and real life far from show business. Each had some earlier experience, so “first major film role” here means a debut or first significant screen part, not a first moment in front of an audience.
Harold Russell, The Best Years of Our Lives

Harold Russell wasn’t an actor when director William Wyler cast him in the 1946 drama. He was a World War II veteran who had lost both hands in a military accident. He played Homer Parrish, a sailor adjusting to civilian life with prosthetic hooks.
The Academy honored him twice for the one performance. He won Best Supporting Actor, and he also received an honorary award for bringing hope to fellow veterans. That makes him a rare double winner for a single role, and he earned both without any prior film career.
Julie Andrews, Mary Poppins

Julie Andrews was already a star on Broadway, known for My Fair Lady and Camelot. Hollywood had passed her over for the film version of My Fair Lady. Walt Disney then cast her as the title nanny in Mary Poppins, her first movie.
She won Best Actress at the ceremony honoring 1964 films. Her screen debut beat several established names, and it launched a film career that soon included The Sound of Music.
Barbra Streisand, Funny Girl

Barbra Streisand brought Fanny Brice to the screen in Funny Girl after playing her on Broadway. The 1968 film was her first. She had been a recording star and stage performer, yet she had never made a movie before.
She won Best Actress, and the result was a tie with Katharine Hepburn for The Lion in Winter. Ties in the major acting categories are very rare. Streisand’s debut win remains one of the most famous in Oscar history.
Haing S. Ngor, The Killing Fields

Haing S. Ngor was a Cambodian physician who survived the Khmer Rouge regime. He had no acting background when he was cast in The Killing Fields (1984). He played Dith Pran, a journalist who endures the genocide in Cambodia, a story close to his own experience.
He won Best Supporting Actor, and he was the first Asian man to win an acting Oscar. His career after the win was short. He was murdered in Los Angeles in 1996.
Jennifer Hudson, Dreamgirls

Jennifer Hudson became widely known as a contestant on American Idol, where she did not win. Dreamgirls (2006) was her feature film debut. She played Effie White, the powerhouse singer pushed out of her group.
She won Best Supporting Actress for the role. Her performance of “And I Am Telling You I’m Not Going” became the film’s signature moment. She went from a reality competition to an Oscar in about two years.
Lupita Nyong’o, 12 Years a Slave

Lupita Nyong’o had just finished the Yale School of Drama when she made 12 Years a Slave. She had worked on smaller projects before, but this was her feature film debut. She played Patsey, an enslaved woman on a Louisiana plantation, in Steve McQueen’s 2013 drama.
She won Best Supporting Actress at the ceremony the following March. The win came in her first major film role. Her performance is still widely cited as one of the strongest debuts of the last twenty years.
These six winners show that an Oscar doesn’t always follow a long apprenticeship. Sometimes the right role and the right life experience arrive together. For all of them, one early performance was enough to earn the industry’s top honor.
