is an American actor. He made his film debut in Alexander Payne's coming-of-age film The Holdovers (2023), portraying troubled teenager Angus Tully. His performance won him the Critics' Choice Movie Award for Best Young Performer in addition to a nomination for the BAFTA Award for Best Actor in a Supporting Role.


From tenth grade he went to Deerfield Academy, a preparatory high school in Deerfield, Massachusetts, as a financial aid student. He was active in the school's theater program, acting in the plays Antigone and Rumors and directing an excerpt from No Exit.


Sessa was discovered by casting director Susan Shopmaker, who offered Deerfield Academy students a chance to audition for The Holdovers since the film was using the academy as a shooting location. Sessa was selected among twelve students who auditioned for the role. In September 2023, Sessa was listed as one of Variety's "10 Actors to Watch for 2023".

He will next appear in Tow, directed by Stephanie Laing and starring Rose Byrne.
