Sadie Sink’s Early Life & Background

Sadie Elizabeth Sink was born on April 16, 2002, in Brenham, Texas, one of five children of Lori and Casey Sink. She has three older brothers, Caleb, Spencer and Mitchell, and a younger sister, Jacey. Her family was primarily interested in sports, but she and Mitchell developed an interest in musical theatre. She made her stage debut at the age of seven as an ensemble member in a community-theatre production of The Best Christmas Pageant Ever in Brenham, and the following year she played Mary Lennox in an A.D. Players production of The Secret Garden. She trained at the Humphreys School of Musical Theatre at Theatre Under the Stars and attended a summer program at the Houston Family Arts Center, and in 2012 her family relocated to New York City, where she alternated between homeschooling, remote study and public school.

Sink performed with Theatre Under the Stars in Houston, playing Susan Waverly in White Christmas in 2011 and the title role in Annie in 2012. She made her Broadway debut at the age of ten in the revival of Annie at the Palace Theatre, where she served as a standby and then alternated in the roles of Annie and Duffy from July 2013 until the show closed in 2014. She made her television debut in a 2013 episode of The Americans, guest-starred in Blue Bloods in 2014, and played series regular Suzanne Ballard in the NBC thriller American Odyssey in 2015. She returned to Broadway the same year as the young Elizabeth II in The Audience, opposite Helen Mirren, and she made her feature-film debut as Kimberly Wepner in Chuck in 2016.

Sadie Sink’s Career

Sink auditioned in September 2016 for the role of Max Mayfield in the second season of Stranger Things. The casting directors initially deemed the fourteen-year-old too old for the part, but she begged and pleaded for the role, attended four callbacks, and won it after a chemistry read with Gaten Matarazzo and Caleb McLaughlin. She lied about her rollerblading experience during the audition and then had to learn to skateboard, taking three-hour lessons daily for two months. Her performance made her a breakout star, and she earned a Screen Actors Guild Award nomination as part of the ensemble. She appeared in The Glass Castle in 2017 and Eli in 2019, and she returned for Stranger Things season three in 2019 to critical praise. In 2021, she played Ziggy Berman in Fear Street Part Two: 1978, doing most of her own stunts, and reprised the role in Fear Street Part Three: 1666, and she starred opposite Dylan O’Brien in Taylor Swift’s All Too Well: The Short Film, which Swift wrote and directed and said she would not have proceeded with if Sink had declined.

Sink’s fourth season of Stranger Things in 2022 brought her some of the most acclaimed work of her career, winning her the Hollywood Critics Association Award for Best Supporting Actress in a Streaming Series, Drama, and a Saturn Award nomination. The same year, she played Ellie, the estranged daughter of Brendan Fraser’s character, in Darren Aronofsky’s The Whale, which premiered at the Venice Film Festival and earned her a Critics’ Choice nomination for Best Young Actor or Actress, and she took the lead role in Dear Zoe. She was named to the Forbes 30 Under 30 list and the Time 100 Next list in 2022. Her later film work includes A Sacrifice in 2024, in which she played Mazzy Monroe opposite Eric Bana, and the Searchlight rock opera O’Dessa in 2025, in which she played the title role.

On stage, Sink returned to Broadway in April 2025 as Shelby Holcomb in John Proctor Is the Villain, earning a Tony Award nomination for Best Actress in a Play. Like Rachel Zegler, who played Juliet on Broadway, Sink made her West End debut as Juliet in Robert Icke’s Romeo and Juliet in March 2026. In 2026, she joined the Marvel Cinematic Universe as Jean Grey in Spider-Man: Brand New Day, a role that had been kept secret until the film’s release and was praised as a standout, and she is set to reprise the role in Avengers: Secret Wars in 2027 and an untitled X-Men film in 2028. She will also executive produce the film adaptation of John Proctor Is the Villain and star in Hiro Murai’s television adaptation of The Marriage Plot. Away from acting, she walked the runway at Paris Fashion Week in 2018 at fifteen, has walked for Miu Miu and Kate Spade New York, became a global ambassador for Armani Beauty in July 2023, and fronted a Prada recycled nylon campaign in March 2025.
