He is the younger brother of filmmaker James Gunn and frequently appears in his productions.
Beyond his two most recognizable roles, Sean Gunn has built a steady career across comedy, science fiction, and superhero genres, contributing both on-screen performances and motion-capture work for some of the highest-grossing films of the past decade. He is also recognized for playing Weasel and Calendar Man in the Warner Bros. film The Suicide Squad (2021) and for reprising Weasel in the animated series Creature Commandos (2024).
Early Life and Background
Sean Gunn was born on May 22, 1974, in St. Louis, Missouri, and is the youngest of six children. His siblings include filmmaker James Gunn, actor and political writer Matt Gunn, screenwriter Brian Gunn, producer Patrick Gunn, and his sister Beth, who works as an employment attorney. Their parents are Leota (Hynek) and James F. Gunn, a retired partner and corporate attorney with the St. Louis law firm Thompson Coburn.
Growing up in a large, accomplished family in the Midwest gave Sean Gunn an early familiarity with creative and professional pursuits. He and his brothers attended St. Louis University High School, a Jesuit institution, where he graduated in 1992. He later enrolled at DePaul University in Chicago, where he trained at The Theatre School and graduated in 1996.
His time at DePaul introduced him to the discipline of stage acting and connected him with future collaborators. The school years in Chicago in the mid-1990s became the foundation for his professional network, including a lasting creative partnership with fellow Goodman School of Drama alum and Gilmore Girls cast member John Cabrera.
Path to Acting
Sean Gunn began his professional acting career shortly after completing his training at DePaul University. His earliest notable screen credit came in 1995 with the independent B-movie Tromeo and Juliet, where he played Sammy Capulet. The role marked his first entry into film and introduced him to low-budget genre production, an environment that allowed him to develop on-set experience quickly.
As the 1990s progressed, he picked up guest spots on television series and small film parts while building his craft. He appeared in projects such as The Specials, in which he played Alien Orphan, also known as Doug, and earned a co-producer credit on the film. These early credits helped him transition from student work into consistent professional employment.
By the end of the decade, Sean Gunn had established enough of a television presence to attract the attention of casting directors working on a new WB drama. That opportunity would soon lead to the role that would define his early career and introduce him to a wide audience.

He also appeared in national commercials as an agent for the text-message information service KGB.com.
In 2000, he guest starred in the second episode of Gilmore Girls as Mick, a DSL cable installer. The brief appearance led to a return in the recurring role of Kirk Gleason, one of the fictional town of Stars Hollow’s most eccentric citizens, a character that would become central to his career.
