Sweden's Hollywood sweetheart could become the Nordic country's first actor to take home an Academy Award in more than four decades at the annual gala on Sunday.
But a forgotten clip of her first televised appearance emerged on Thursday, showing an eight-year-old Vikander demonstrating her acting talent as early as back in 1997.
In the video by broadcaster TV4, she performs on a Swedish talent show where children imitate famous artists by lip-syncing to their most popular hits, competing against each other in front of a jury.
When asked by the host what she wants to be when she grows up, she quickly answers: "Actor".
And revelling in the spotlight, young Vikander brings to life a song from the musical 'Kristina from Duvemåla' by fellow Swedes Björn Ulvaeus and Benny Andersson, about a group of Swedes emigrating to the United States in the 19th century.
It's pretty serious stuff for an eight-year-old, and she is clearly not afraid of tackling the rather serious subject matter of the song, called 'Du måste finnas', ('You Have to Be There'), and is about a woman questioning the existence of God after her child dies.
She totally wins the talent show, by the way. Watch the rest of the video here.
More recently, the Swedish starlet, now 27 years old, has received plenty of attention for her roles in Hollywood movies including 'Anna Karenina', 'Ex Machina' and Julian Assange biopic 'The Fifth Estate'.
On Sunday she could pick up an Oscar for best actress in a supporting role for her performance in Scandinavian trans-gender movie 'The Danish Girl'. In the acclaimed film she stars opposite Eddie Redmayne, who is nominated in the best actor category.
Vikander is competing against US actress Rooney Mara, nominated for her role in 'Carol' and well known in Sweden for her depiction of Lisbeth Salander in the American adaptations of the Swedish Millennium series, penned by Stieg Larsson.

Rachel McAdams and Jennifer Jason Leigh have also made the shortlist as well as the UK's Kate Winslet.
The last Swedish actor to win an Oscar was Ingrid Bergman in 1974 for her role in The Orient Express.
The team behind the Swedish movie 'The 100-Year-Old Man Who Climbed Out of the Window and Disappeared' has additionally been nominated in the 'Best Makeup and Hairstyling' category. The film, produced in 2013 but released globally last year, saw 51-year-old Robert Gustafsson play retirement home escapee Allan Karlsson.
