In short: Justin Kuritzkes began his career as an internet personality, gaining fame for his 2011 viral video Potion Seller. Today, he is a prominent screenwriter behind major cinematic releases. His journey from online comedy to collaborating with director Luca Guadagnino highlights a unique evolution in modern creative storytelling and professional trajectory.

Born in Los Angeles in 1990, Kuritzkes developed an early interest in writing, earning recognition for his play An Autobiography of My Brother while still in high school. He later pursued philosophy and literary arts at Brown University, graduating in 2012. During his undergraduate years, he became involved in the Occupy movement and began experimenting with digital content, recording videos via the Photo Booth application. His most enduring digital legacy, Potion Seller, became a cultural touchstone that even earned parodies in The New Yorker.

Kuritzkes transitioned into professional playwriting and literature, receiving MacDowell Fellowships in 2012 and 2016 and publishing his novel Famous People in 2019. His breakthrough in film arrived in 2021 when his spec script for Challengers appeared on The Black List. This success led to a prolific partnership with director Luca Guadagnino, resulting in screenplays for both Challengers and the adaptation of William S. Burroughs' 1985 novel Queer. By 2023, industry analysts identified him as a rising talent to monitor within the screenwriting landscape.

His recent career has been marked by high-profile assignments and shifting project statuses. He has been linked to adaptations of Don Winslow's City on Fire and a project inspired by Mike Nichols. Although a planned collaboration involving Daniel Craig and the character Sgt. Rock was cancelled in 2025, Kuritzkes continues to work on major studio features, including providing literary contributions to the Marvel Cinematic Universe film Spider-Man: Brand New Day in 2026. He resides in New York City with his wife, the filmmaker and playwright Celine Song, whom he married in 2016.
