Liam Oh is a rising actor who has captured global attention following his breakout performance as Ray McAffey in the Netflix military dramedy series Boots. Born in 1999 and raised on the outskirts of Chicago alongside his three brothers, Oh possesses a multicultural background of Korean and Irish ancestry. His dual heritage and personal experiences as a mixed-race actor have heavily shaped both his identity and his approach to representation in modern television.
The curiosity surrounding his heritage stems from both his unique name combination—merging an Irish first name with an East Asian surname—and his milestone role on screen. In Boots, which adapts memoir material chronicling recruit life in the early 1990s US Marine Corps, Oh portrays a mixed-race Korean character navigating prejudice and expectations during boot camp. For Oh, taking on this role marked the first time in his professional career that he was able to portray an explicitly Asian character on screen, making the project a deeply personal and affirming milestone.
Early Life and Multicultural Roots
Growing up in the Chicago area with three brothers provided Oh with a grounded Midwestern upbringing before he pursued formal training. He attended Northwestern University, refining his craft through local theater and regional stage productions. His artistic journey eventually led him to relocate to New York City to expand his opportunities in professional acting.
Being of mixed Korean and Irish descent—frequently discussed in terms of a blended or hapa identity—means Oh belongs to an expanding group of artists bringing multi-ethnic narratives to the mainstream. Rather than treating his background as a mere footnote, Oh has spoken about how navigating these dual cultural lineages informs his worldview and helps him connect with complex characters who exist between distinct cultural worlds.

The Breakthrough Role in Netflix's Boots
Oh's career trajectory shifted dramatically while he was performing on stage. In 2023, during the intermission of a live performance of Once at Glencoe's Writers Theatre where he played Andrej, he received word that he had been cast in the Netflix series Boots. He boarded a plane shortly after to dive straight into a rigorous production schedule.
Created by Andy Parker and inspired by veteran Greg Cope White's memoir The Pink Marine, Boots follows a closeted teenager and his best friend, Ray McAffey (played by Oh), as they enlist in the Marine Corps during the early 1990s. The series explores themes of camaraderie, survival, and identity under the military's historical restrictions.
The physical demands of production required intense preparation, including mini-bootcamps held on the fly before filming episodes. This fast-paced environment allowed the cast to build genuine camaraderie on screen. The series quickly climbed streaming charts, earning critical praise for its nuanced handling of historical military restrictions and diverse personal backgrounds.
Navigating Representation in Modern Media
The interest in Liam Oh's ethnicity reflects a broader cultural shift within the entertainment industry. Audiences increasingly look for authentic representation where multicultural actors can bring their lived realities to complex roles. For Oh, playing Ray McAffey wasn't just about stepping into a high-profile streaming series; it was an opportunity to give visibility to mixed-race identities that have historically been underrepresented or flattened in Hollywood casting.
His journey underscores the evolving definition of identity in the global spotlight. By embracing both his Irish and Korean roots, Oh stands as an example of a new generation of performers redefining what it means to lead major television projects without being confined to rigid casting archetypes.
