## Training and early career
Dunn is a graduate of the [University of North Carolina School of the Arts](https://www.edgepedia.org/university-of-north-carolina-school-of-the-arts), a conservatory she credits with letting her try many styles before professional work began: "You do Ibsen, French farce, Shakespeare — the good thing about starting with a conservatory before you jump into work is that you can try out so many different styles."[1](https://www.imdb.com/name/nm1384840/) • [2](https://filmmakermagazine.com/70751-trieste-kelly-dunn/) Her first screen credit, according to a career survey of her filmography, was voicing the character Miho in the English version of the 1995 animated mini-series *Kekkon*; she did not act again on screen until short films in 2003.[3](https://thebiography.org/all-about-trieste-kelly-dunn-age-husband-net-worth-family/)
Her early screen work included a small part in [Gregg Araki](https://www.edgepedia.org/gregg-araki)'s *[Mysterious Skin](https://www.edgepedia.org/mysterious-skin)* (2004) and guest spots on *Law & Order: Special Victims Unit* and *Canterbury's Law*.[3](https://thebiography.org/all-about-trieste-kelly-dunn-age-husband-net-worth-family/) • [4](https://www.allocine.fr/personne/fichepersonne-146410/filmographie/) In 2006 she played Deora Frances Bodley, one of the passengers aboard the hijacked flight, in Paul Greengrass's docudrama *United 93*, and took supporting parts on *Bored to Death* and *Fringe*.[1](https://www.imdb.com/name/nm1384840/) • [2](https://filmmakermagazine.com/70751-trieste-kelly-dunn/)
## The 2010 independent-film year
**2010 marked her arrival in independent cinema.** She starred as Gail in Aaron Katz's mystery *Cold Weather*, as Donna in Zach Clark's beach-party comedy *Vacation!*, and as Sunny in Brett Haley's *The New Year*, three films with, as *Filmmaker Magazine* put it, "very different tones and directing styles" in which "Dunn is each film's center."[2](https://filmmakermagazine.com/70751-trieste-kelly-dunn/) The magazine placed her on its 25 New Faces of 2010 list that July, and critic Todd McCarthy wrote of her *The New Year* performance at the Los Angeles Film Festival that she was "very good indeed" in a film that keeps its camera fixed on a single performer.[2](https://filmmakermagazine.com/70751-trieste-kelly-dunn/) On the review aggregator Rotten Tomatoes, *The New Year* stands as her highest-rated film at 100 percent.[5](https://www.rottentomatoes.com/celebrity/trieste_kelly_dunn)
She continued in independent features through the following years, including the lead as Allie in Geoff Marslett's *Loves Her Gun* (2013), a character study in which her character moves to Texas after a violent attack in New York; the film was shot largely out of sequence with improvised dialogue, and Dunn fired live ammunition on camera.[6](https://moveablefest.com/interview-trieste-kelly-dunn-fires-loves-gun/) Her other 2010s film credits include *Applesauce* (2015), *[Blame](https://www.edgepedia.org/blame-2017-film)*, *Infinity Baby*, and *The Misogynists* (all 2017), *[Girl on the Third Floor](https://www.edgepedia.org/girl-on-the-third-floor)* (2019), and *Lousy Carter* (2023).[1](https://www.imdb.com/name/nm1384840/)
## Television: Banshee and Blindspot
Dunn's best-known television role is Deputy Siobhan Kelly on Cinemax's action series *Banshee*, which she played across all four seasons from 2013 to 2016 in 34 episodes, plus the companion shorts *Banshee Origins*.[1](https://www.imdb.com/name/nm1384840/) A review of the first-season episode "The Kindred" singled out her performance as the deputy, traumatized after her first killing in the line of duty and then targeted in revenge by a biker gang, as "a brilliant performance" that brought the character fully into the light.[7](https://www.denofgeek.com/tv/banshee-episode-5-review-the-kindred/) In a 2016 interview she described the difference between cable and network production: cable's shorter seasons give writers more time to develop stories, while network television is "much more frenetic."[8](https://lovingseries.com/2016/04/18/entrevista-exclusiva-con-trieste-kelly-dunn/)
While *Banshee* was still running she joined NBC's *Blindspot* as CIA Agent Allison Knight, a recurring role she held from 2015 to 2020.[1](https://www.imdb.com/name/nm1384840/) Her other television credits include *Believe* (2014, as FBI Special Agent Elizabeth Ferrel), a 2016 guest spot on CBS's *Bull* as Captain Taylor Mathison, a commercial airline pilot whose crash trial becomes a test of jurors' gender bias, *Manhunt* (2017), *The Passage* (2019), and *Elementary* (2018).[1](https://www.imdb.com/name/nm1384840/) • [9](https://www.tvline.com/casting-news/bull-casts-trieste-kelly-dunn-cbs-series-740524/)
