Gus Birney

Gus Birney, born Augusta Marsh Birney on July 27 1999, is an American actress who has quickly become a notable presence in contemporary television and theatre. The daughter of acclaimed actors Reed Birney and Constance Shulman, she grew up immersed in a creative household that nurtured her early interest in performance, and she began her professional career in 2012, steadily building a résumé that spans stage, film, and streaming series. Birney’s stage debut came in 2016 when she portrayed Rosa in Tennessee Williams’s The Rose Tattoo at the Williamstown Theatre Festival, sharing the spotlight with veterans such as Marisa Tomei, Christopher Abbott, and Lindsay Mendez, an experience that honed her craft and earned critical praise for her nuanced delivery. She transitioned to screen work with a film debut in the romantic comedy Here and Now (2018) opposite Sarah Jessica Parker, and soon after appeared in Charlie Kaufman’s psychologically intricate Netflix drama I’m Thinking of Ending Things (2020) and the Hulu teen comedy Plan B (2021). Television audiences may recognize Birney from her roles in the science‑fiction horror series The Mist (2017), the superhero drama Jessica Jones (2019), and the dark comedy Insatiable (2019), but her standout performance as Jane Humphreys in Apple TV+’s period series Dickinson (2019‑2020) cemented her reputation for blending wit with emotional depth. From 2022 to 2023 she contributed to the satirical horror series Shining Vale, earning a Saturn Award nomination for Best Young Actor in a Television Series. Her theatrical achievements continued with the off‑Broadway revival of Lorraine Hansberry’s The Sign in Sidney Brustein’s Window (2023), where she played the complex character Gloria Parodus opposite Oscar Isaac and Rachel Brosnahan, a performance described as “excellent” by TheatreMania. The production’s subsequent transfer to Broadway marked Birney’s Broadway debut, a milestone she described as “one of the most transformative experiences of my life.” In 2024 she appeared in the adaptation of Tadeusz Slobodzianek’s Our Class at the Brooklyn Academy of Music, delivering a “heartbreaking” portrayal of Dora, a young Jewish mother confronting the looming tragedy of the 1941 Jedwabne pogrom. Birney’s career thus reflects a dynamic range and a commitment to challenging, emotionally resonant storytelling across mediums.
