It's a list that could grow this year. Eddie Redmayne, who won Best Actor last year for The Theory of Everything, is up again in the same category for The Danish Girl. And Emmanuel Lubezki, who won Best Cinematography Oscar in 2013 for Gravity and in 2014 for Birdman, is up again this year for The Revenant. If he wins, he would score an even rarer Oscar three-peat. The Revenant's director, Alejandro G. Iñárritu, won Best Director for Birdman last year; a win Sunday night would make him the third director in history with back-to-back nods. (And if the film wins Best Picture, he'd become the first director to win Best Director and Best Picture consecutively, too.)
Here's a look at 10 others who scored back-to-back wins.
Probably the best-known celeb to win consecutive Oscars in recent memory, Hanks won his first Best Actor Oscar at the 1994 Academy Awards for his groundbreaking role in Philadelphia. The following year, Hanks won again for Forrest Gump. And that's what you call a matching set.
But what's perhaps even more impressive than Hanks' dual wins is the Oscar collection that Disney music maestro Alan Menken picked up between 1992 and 1993. In 1992, Menken won not one but two Oscars for his work on Beauty and the Beast, for Best Original Song and Best Original Score. The following year, Menken repeated that success on both counts, winning Best Original Song and Best Original Score again for Aladdin. And if The Little Mermaid had hit theaters in 1990 rather than 1989, he might have scored a twofold threepeat, as he won in both categories for that film too.
Robards earned the Oscar for Best Supporting Actor in 1977 for his role as Washington Post editor Benjamin Bradlee in All the President's Men. In 1978, Robards won an additional Oscar for Best Supporting Actor for playing a different famous man of letters – Dashiell Hammett, whom he portrayed in Julia.
As If You Didn't Love Eddie Redmayne Enough Already, Now Watch Him Play Piano
When it comes to Oscar records, Katharine Hepburn is the queen. Not only is she the person with the most wins – four, for Morning Glory, Guess Who's Coming to Dinner, The Lion in Winter and On Golden Pond – she's also famous for being one of the celebs who always declined to accept her award. She won in 1968 for Coming to Dinner, and then in 1969 she won again for Lion, though in that year she tied with Barbra Streisand, who also won Best Actress for Funny Girl.
The famed composer managed to score back-to-back wins not once but twice. First, he won Best Score in both 1959 and 1960, for Gigi and Porgy and Bess. And then he did it again in the same category in 1964 and 1965, for Irma la Douce and My Fair Lady.
Breakfast at Tiffany's proved to be a great success for Mancini, who in 1962 won Oscars for both his score for the film as well as his original song, the love theme "Moon River." The following year, Mancini picked up the Best Original Song again for "Days of Wine and Roses," from the movie of the same name.
Joseph L. Mankiewicz
The famed director won two Oscars in 1950 – Best Director and Best Screenplay, both for his romantic drama A Letter to Three Wives. The following year, Mankiewicz picked up another Oscar – Best Director, again, and this time for the classic All About Eve.
We'd love to get a look at John Ford on the Oscars stage, but you're going to have to instead accept a clip of John Wayne accepting as his proxy when the legend won Best Director in 1953 for The Quiet Man. That was the first televised Oscars ceremony, but Ford had previously scored back-to-back wins in 1941 and 1942, for the classics The Grapes of Wrath and How Green Was My Valley, respectively.
Let's hear it for newsreels! This one shows not only Spencer Tracy winning the second of two back-to-back Best Actor Oscars – for Captains Courageous in 1938 and Boys Town in 1939 – but also Bette Davis wining for Jezebel and Deanna Durbin wining the Juvenile Award for general youthful onscreen awesomeness.
The only actress aside from Hepburn to win consecutive acting awards in Luise Rainer, who won in 1937 and 1938 for The Great Ziegfeld and The Good Earth, respectively. It's a trip to see how different Academy Award presentations worked back in the day, but it's also worth praising Rainer for keeping her acceptance speech very short and very sweet. "Thank you very much. I'm very happy… that I got it," she says, before erupting into laughter. Honest! To the point! Prospective winners of 2016, please take note!
