Sean Gunn (born May 22, 1974) is an American actor with a career that spans more than three decades across television and film. He first gained widespread recognition for playing the quirky Kirk Gleason on the long-running drama Gilmore Girls. He later became a fixture in major superhero productions, playing Kraglin Obfonteri in the Marvel Cinematic Universe and Weasel in Warner Bros. and DC projects. The younger brother of filmmaker James Gunn, he has frequently collaborated with his brother on a wide range of projects in Hollywood.
Early Life and Background
Sean Gunn was born in St. Louis, Missouri, the youngest of six children. His parents are Leota (Hydek) and James F. Gunn, a retired partner and corporate attorney with the law firm Thompson Coburn in St. Louis. He grew up in a large, accomplished family that includes his filmmaker brother James Gunn, actor and political writer Matt Gunn, and screenwriter Brian Gunn.
He attended St. Louis University High School, a Jesuit institution, where he graduated in 1992. He was surrounded by creative siblings who would later work in film, television, and writing, and his early years in St. Louis gave him a strong Midwestern foundation before he pursued acting full time.
After high school, Gunn moved to Chicago to study at The Theatre School at DePaul University, where he earned his Bachelor of Fine Arts degree. While in Chicago, he met fellow aspiring actor and filmmaker John Cabrera, beginning a long creative partnership that would shape his early professional work.
Path to Acting
Sean Gunn began his professional acting career in 1995, the same year he was still studying at DePaul University. His earliest screen role was as Sammy Capulet in the cult B-movie Tromeo and Juliet, directed by Lloyd Kaufman. The low-budget production gave him valuable on-set experience and a foothold in the independent film world.
Throughout the late 1990s, he built his résumé with guest spots on several popular television series, including Angel, 3rd Rock from the Sun, Yes, Dear, and Andy Richter Controls the Universe. He also took on a meaningful film role as the Alien Orphan, also known as Doug, in the superhero comedy The Specials, where he also received a co-producer credit. These early roles showcased his range in both comedy and genre storytelling.
