Addisyn Grace Cain is an actress, filmmaker, writer, and model from Little Rock, Arkansas, who grew up between Texas and Arkansas alongside her sister, Stella.

She appears as Brandi Combs in Mouse, an upcoming SAG-AFTRA indie feature directed by Kelly O’Sullivan and Alex Thompson (Ghostlight), which premiered at the Berlin International Film Festival (Berlinale) in the Panorama category February 2026.

Boyle, portraying the teenage daughter lead opposite Meredith Riley Stewart. The film is set for a 2026 release. This marks her first lead role in a feature, where she was challenged both mentally and physically with conquering emotions and field hockey.

Cain has also written, directed, and starred in the short film Fragments of Innocence (2024-2025), for which she won First Place for the Thea Foundation Scholarship Competition, and is developing a narrative featurette titled Baby Blues in collaboration with her sister, Stella Reese Cain.

Her experience also includes commercial and modeling work, including leading the Team USA × Coca-Cola campaign "The Halftime Cheers," which aired across North American stadiums and arenas in 2024. In terms of modeling, Addisyn had the privilege of getting to be a part of an eight-page editorial feature for Cosmopolitan Magazine Bulgaria in the Summer of 2025. Addisyn's work has been mentioned in Variety, The Hollywood Reporter, IndieWire, IonCinema, Cinema Express, and the Arkansas Times.
