Rosabell Laurenti Sellers is an Italian-American actress who earned global recognition for playing Tyene Sand in HBO's Game of Thrones and starring in the hybrid live-action and animated series Mia and Me. Born in Santa Monica, California, and raised between New York City and Rome, she built an international career across European and American television and film productions.
Her trajectory spans early stage performances in Italy, breakout young adult fantasy roles, and mature science fiction and fantasy appearances on global streaming platforms. Beyond acting, she maintains active commitments to community service and advanced theatrical training.
Early Life and Artistic Background
Born on March 27, 1996, Sellers grew up immersed in the arts. Her mother, Mary Sellers, is an American actress and director, while her father, Fabrizio Laurenti, is an Italian filmmaker and screenwriter. This creative family environment heavily influenced her early entry into the performance space.
She spent her childhood years in New York City before her family relocated to Rome. In Rome, she began acting on stage at a very young age, joining the Eurassia theatrical company for several productions. Before transitioning to screen acting, she gained foundational discipline through extensive physical and vocal training, including tap dance and equestrian competitions. Being raised in a bilingual household allowed her to master both English and Italian fluently, opening doors to casting calls in multiple languages across Europe and North America.
Early Television and Breakthrough Roles
Sellers made her professional screen debut in the mid-2000s, appearing in Italian television projects such as the mini-series E poi c'è Filippo and the television movie L'amore e la guerra. In 2009, she gained critical notice in Italy for portraying a young Anne Frank in the television film Mi ricordo Anna Frank.
Her first major international breakthrough came in 2011 when she was cast as Mia in the fantasy series Mia and Me. Playing the live-action lead while also providing the voice for the animated elf version across the first two seasons introduced her to a massive young audience worldwide. Shortly after, she secured a prominent role as Valentina Rengoni in the hit Italian family drama series Una grande famiglia (The Family), cementing her status as a rising star in European television.
Entering the Global Stage: Game of Thrones
In 2015, Sellers joined the cast of HBO's fantasy phenomenon Game of Thrones for its fifth season. She was cast as Tyene Sand, the youngest of the three notorious Sand Snakes—the warrior daughters of Oberyn Martell—alongside Jessica Henwick and Keisha Castle-Hughes.
Portraying Tyene required intense physical preparation, including combat training with dual daggers and whips. Her character became famous for using poisoned weapons and a charming yet lethal demeanor. Appearing across nine episodes from season five through season seven, Sellers experienced a massive surge in global visibility. Her dramatic exit during the seventh season marked a memorable conclusion to her character's arc in the capital of Westeros.
Expanding Into Sci-Fi and International Projects
Following her tenure in Game of Thrones, Sellers focused on refining her craft and expanding her range into science fiction and international co-productions. In 2017, she relocated to London to study at the prestigious Guildhall School of Music and Drama, honing her classical training.
As streaming platforms expanded international talent pools, Sellers secured major roles in speculative fiction series:
- Spides (2020): She starred as Nora Berger in this Syfy science fiction thriller series, investigating an alien drug epidemic in Berlin.
- Willow (2022): She appeared as Lili in the Disney+ fantasy sequel series, returning to high fantasy settings.
- The Swarm (2023): She played Alicia Delaware in this high-budget international eco-thriller series produced for European networks.
These projects demonstrated her capability to anchor complex, multilingual narratives and hold her own alongside veteran ensembles.
Philanthropy and Personal Life
Outside of acting, Sellers maintains a strong commitment to social activism and charitable work. During her years living in Italy, she regularly volunteered at Rome's Comunità di Sant'Egidio soup kitchen, serving meals to those in need.
She has also lent her voice to campaigns like Veto the Squito, an initiative focused on raising funds for insecticide-treated bed nets to prevent malaria in Africa. Furthermore, she has collaborated with anti-discrimination groups such as the League Against Racism and Anti-Semitism. Her balance of professional acting commitments and grassroots humanitarian work defines her public profile away from the screen.
