## Early career and training
Blackehart was born in New York City.[3](https://www.rottentomatoes.com/celebrity/stephen_blackehart) He trained as a stage actor, studying with [Uta Hagen](https://www.edgepedia.org/uta-hagen) at [HB Studio](https://www.edgepedia.org/hb-studio) and at the [London Academy of Music and Dramatic Art](https://www.edgepedia.org/london-academy-of-music-and-dramatic-art) (LAMDA), and accumulated more than 50 off-Broadway and London stage credits before his screen career took hold.[7](https://www.imdb.com/name/nm0002888/bio) He was also a regular on the sketch comedy show *The Tromaville Cafe*, where he originated the role of Felix, the French Trickster.[6](https://ijr.com/x/stephen-blackehart-Q7608723)
His first screen role of note was Benny Que in *Tromeo and Juliet* (1996), the Shakespeare-inspired Troma Entertainment film written by James Gunn. In a 2023 interview, Blackehart said he and Gunn met while shooting the film in 1995 and have worked together since: "We have so much of a similar sensibility about things that I trust him and he trusts me without having to say much."[4](https://freaksugar.com/interview-actor-stephen-blackehart-on-his-role-in-guardians-of-the-galaxy-vol-3/) Gunn later loosely based the character of Steve, played by [Ty Burrell](https://www.edgepedia.org/ty-burrell), in *Dawn of the Dead* (2004) on Blackehart.[7](https://www.imdb.com/name/nm0002888/bio)
## B-movie years
Through the 2000s Blackehart built a substantial resume in low-budget genre film, appearing in *Retro Puppet Master* (1999, as the First Servant), *The Ghouls* (2003), *100 Million BC* (2008), *The Terminators* (2009), *Mega Shark vs. Giant Octopus* (2009), and *Battle of Los Angeles* (2011).[3](https://www.rottentomatoes.com/celebrity/stephen_blackehart) • [9](https://www.thetvdb.com/people/463356-stephen-blackehart) His best-reviewed film from this period is the [H. P. Lovecraft](https://www.edgepedia.org/h-p-lovecraft) adaptation *The Whisperer in Darkness* (2011), in which he played Charlie Tower; it holds an 86 percent critics rating on Rotten Tomatoes, the highest of his listed films.[3](https://www.rottentomatoes.com/celebrity/stephen_blackehart) He also appeared in Gunn's *Super* (2010) as Quill and in *The Belko Experiment* (2016) as Robert Hickland.[9](https://www.thetvdb.com/people/463356-stephen-blackehart)
## The James Gunn collaborations
Blackehart has appeared in nearly every film and series Gunn has directed since their Troma days, alongside other Gunn regulars such as [Michael Rooker](https://www.edgepedia.org/michael-rooker), Nathan Fillion, and [Sean Gunn](https://www.edgepedia.org/sean-gunn).[6](https://ijr.com/x/stephen-blackehart-Q7608723) In the [Marvel Cinematic Universe](https://www.edgepedia.org/marvel-cinematic-universe) he has played two characters: the Knowhere dispatcher, named Steemie Blueliver, in *Guardians of the Galaxy* (2014), *The Guardians of the Galaxy Holiday Special* (2022), and *Guardians of the Galaxy Vol. 3* (2023), and the Ravager Brahl in *Guardians of the Galaxy Vol. 2* (2017).[5](https://marvelcinematicuniverse.fandom.com/wiki/Stephen_Blackehart) He also played Briscoe in Gunn's *The Suicide Squad* (2021) and Travis in *Brightburn* (2019), which Gunn produced.[1](https://www.imdb.com/name/nm0002888/)
When Gunn moved to [DC Studios](https://www.edgepedia.org/dc-studios), Blackehart followed. Gunn cast him as Sydney Happersen, one of [Lex Luthor](https://www.edgepedia.org/lex-luthor)'s henchmen, in *Superman* (2025); Happersen is a minor comics character who first appeared in 1987's *Superman* Vol. 2 #2 by John Byrne.[10](https://www.gamesradar.com/entertainment/dc-tv-shows/peacemaker-season-2-easter-eggs/) DC's own blog singled out the hair and makeup work that transformed Blackehart for the role.[11](https://www.dc.com/blog/2025/07/14/rounding-up-the-easter-eggs-in-superman) Happersen carried over into *Peacemaker* season 2 (2025), where the character helps Rick Flag Sr. use Luthor's technology, and Blackehart is credited with Sydney Happersen in the sequel *Man of Tomorrow*, scheduled for 2027.[12](https://www.cinemablend.com/superheroes/peacemaker-season-2-lex-luthor-minions-why-one-specifically-agreed-help-rick-flag-sr) • [9](https://www.thetvdb.com/people/463356-stephen-blackehart) A post-credits scene in *Peacemaker* season 2 returned to Happersen in a lab; Gunn called it "truly the foulest post-credits ever" and said an even cruder version had been cut.[13](https://www.gamesradar.com/entertainment/superhero-shows/james-gunn-says-peacemakers-foulest-post-credits-scene-was-originally-way-way-worse/)
In interviews around the DCU projects, Blackehart has described how the Gunn collaborations work: he usually does not learn about a role until it is definite, often about a month before it happens, and he does not mind the uncertainty.[4](https://freaksugar.com/interview-actor-stephen-blackehart-on-his-role-in-guardians-of-the-galaxy-vol-3/)
## Other work
Beyond acting, Blackehart has worked as a producer, casting director, and in sound and camera departments.[14](https://www.tvguide.com/celebrities/stephen-blackehart/credits/3030101152/) His producing credit of note is *LolliLove* (2004), [Jenna Fischer](https://www.edgepedia.org/jenna-fischer)'s mockumentary, which Troma picked up for distribution and which DVD Talk designated a "Collector's Series" disc on video release.[6](https://ijr.com/x/stephen-blackehart-Q7608723) His television appearances include *Grey's Anatomy*, *Star Trek: Deep Space Nine*, *The Orville* (as Krill officers, 2019 to 2022), and *NCIS: Origins* (2025).[6](https://ijr.com/x/stephen-blackehart-Q7608723) • [1](https://www.imdb.com/name/nm0002888/)
A recurring claim that he is related to [Marlon Brando](https://www.edgepedia.org/marlon-brando) is false by his own account. In a 2006 interview with Troma co-founder [Lloyd Kaufman](https://www.edgepedia.org/lloyd-kaufman), Blackehart said, "I am no relation to him that I know of," attributing the story to anonymous internet posts that spread after Brando's death.[7](https://www.imdb.com/name/nm0002888/bio)
## Personal life
Blackehart was married to Mercedes Blackehart from 2006 to 2010.[7](https://www.imdb.com/name/nm0002888/bio)
