Having appeared in her sisters' videos when she was small, Elizabeth began to go on auditions for other projects when she was in the fourth grade. By the time she was ten Elizabeth landed a small role in a local commercial. However, the auditions came at a price. Elizabeth found she had less time for other interests: ballet and sports. She decided to quit acting.
By age 16, Elizabeth began studying Russian theater, which resparked her interest in acting. In 2009, during her sophomore year, Elizabeth became the understudy for the Nicole Halladay character in the Broadway show Impressionism.
It was during this time that the youngest Olsen sister met her agent. Together they decided that theater would be the path for Elizabeth. This decision was partly motivated by the way the media had treated her older sisters after they had been thrust to the spotlight as babies.
However, Elizabeth still auditioned for movies, landing her first role six months after she began. The role was Zoe, Catherine Keener's character's daughter in Peace, Love and Misunderstanding. As she was preparing to begin filming, she came across the script for Martha Marcy May Marlene. After falling in love with the script and being cast as the main character—a young girl escaping from a cult—Elizabeth drove back and forth between both sets until filming was completed on both.
The 2011 film became a film festival darling and landed high praise for Elizabeth's performance.
After Martha Marcy May Marlene, Elizabeth focused on smaller films like Silent House, Liberal Arts and Red Lights. She then starred in Godzilla (2014) and I Saw the Light (2015) before being cast in the key role of Wanda Maximoff / Scarlet Witch in The Avengers: Age of Ultron (2015), which would lead to many more appearances in Marvel films, including Captain America: Civil War (2016) and Avengers: Infinity War (2018). She also starred opposite her Avengers co-star, Jeremy Renner, in Wind River (2017).
Recently, she reprised her role as Wanda Maximoff/Scarlet Witch for the Disney+ series WandaVision (2020).
