Sierra Nicole McCormick was born on October 28, 1997 (Sierra McCormick age: 22) in Asheville, North Carolina. McCormick was raised in Palm Springs, California and has a sister, Kayla.
McCormick’s first television appearance was on the series ‘Til Death, in which she had a small, uncredited cameo. In the same year, she was chosen to be on the second season of Are You Smarter Than a 5th Grader? after attending several castings and auditions.
McCormick told uInterview that being on the game show was the first acting job that gave her “a taste of what being on set is like.” She described the audition process and the time spent filming as an experience that “loosened me up in front of camera and got me accustomed to being in front of camera, and being myself in front of camera, and being real in front of camera.”
In 2010, McCormick played Susan Kushner in the family film Ramona and Beezus alongside Joey King and Selena Gomez. Shortly after, McCormick was cast as child prodigy Olive Doyle on the Disney TV series A.N.T. Farm, which propelled her to mainstream attention. McCormick starred alongside China Anne McClain, who she had previously worked with on the film Jack and Janet Save the Planet in 2008. McCormick played the role on A.N.T. Farm from 2011 to 2014. She also appeared in another Disney show, Jessie, during the same time frame.
In 2011, McCormick played Alice in Disney’s movie Spooky Buddies, for which she won Young Artist Awards Best Performance in a DVD Film – Young Ensemble Cast for her role.
In 2019, McCormick played Fay Crocker in the science fiction film The Vast of Night alongside Jake Horowitz. McCormick has received a special mention from the 27th Hamptons International Film Festival Jury Awards for her role in the film.
McCormick spoke to uInterview in an exclusive interview on her 2019 film The Vast of Night. She revealed that her favorite scenes to film were the ones she spent working with the switchboard as well as the scenes with costar Horowitz in the car, citing their moments of banter as the most fun to film.
McCormick revealed that she and Horowitz spent a large amount of time rehearsing in order to establish their chemistry. “Most of [our chemistry] is in no small part to Andrew [Patterson, director] because he had us rehearse extensively before we ever set foot in front of camera,” McCormick said.
Her favorite scene to watch? “Gail [Cronauer]/Mabel’s monologue. Getting to sit there on the day and witness that… she’s an incredible actress. I learned a lot while just getting to sit in on that scene and listen to her.”
So what did McCormick think of extraterrestrial life, the subject of the film? “I definitely always believed in extraterrestrial life … unexplained events and occurrences, that’s like, my s—,” McCormick said with a laugh. “It was definitely one of little Sierra’s goals to be in a movie that’s about some creepy, unexplained occurrence or disappearance and I think I lived up to it. I think little Sierra’s really happy.”
McCormick resides in Los Angeles. McCormick has been outspoken about her support for the Black Lives Matter movement.
In an exclusive chat with uInterview, McCormick described herself as an extrovert. In the midst of the coronavirus pandemic and the subsequent lockdown of cities around the world, McCormick jokingly said, “I’m an extrovert, so I’m not doing great.” McCormick has turned to watching movies and practicing yoga during her extended time at home.
