The actor opens up about his role for the first time, calling it 'special.'
Warning: This article contains spoilers about David Dastmalchian’s role as Gareth in Dexter: Resurrection.
Dexter: Resurrection boasts one of the most impressive ensemble casts in recent television memory. From established A-listers to critically acclaimed character actors, the show’s first season is stacked with talent.
Among the standout names is David Dastmalchian—an actor known for his unforgettable roles in both indie gems and blockbuster hits—who joins the Dexter universe in a guest star capacity. But make no mistake: his role is anything but minor.
David Dastmalchian Joins Dexter: Resurrection as "The Gemini Killer"
Dastmalchian is one of four high-profile guest stars revealed to be joining the Dexter franchise's new chapter. And like the others, his appearance will leave a lasting impact. Ahead of the official trailer's release, details surrounding his character began to surface online—and they did not disappoint.
He plays Gareth, a notorious serial killer ominously dubbed “The Gemini Killer,” named for his chilling compulsion to kill in pairs. Far from being a mere plot device, Gareth is described as a highly intelligent predator who has eluded the FBI for years. His infamy is such that his crimes have inspired true-crime books, podcasts, and films within the show's universe.
Gareth and the Club of Serial Killers
The trailer for Dexter: Resurrection offered a haunting first glimpse at Gareth, placing him within a disturbing and intriguing context. He appears as part of an underground group led by Leon Prater (Peter Dinklage), a wealthy serial killer enthusiast obsessed with assembling others like him. Prater’s dark mission is made possible with the help of his enigmatic right hand, Charley, portrayed by Uma Thurman.
This twisted "serial killer club" immediately adds a sinister new layer to the Dexter narrative, and Dastmalchian’s character seems to play a central role in its operation.
Dastmalchian on the Challenge of Playing Gareth
In a recent interview with RadioTimes.com, Dastmalchian opened up—carefully—about taking on the role of Gareth. He shared:
“There are things about this character that are very specific and special, and I've never gotten to do it before with any role I've ever played. I've always been scared of—but excited by—the challenge of something that is new or different for me. So just know that going to prepare for the role meant thinking about things in a way that I had not really done before.”
For an actor who’s played everything from tormented souls to comic-book villains, that’s saying a lot. Dastmalchian’s commitment to diving deep into uncharted psychological territory suggests that Gareth won’t just be another killer-of-the-week—he could become one of the most memorable adversaries in Dexter’s dark legacy.
Could Gareth Be a Game-Changer for the Dexter Franchise?
With his chilling moniker, complex psychological profile, and connection to a secret society of serial killers, Gareth has all the makings of an iconic Dexter villain. David Dastmalchian's track record and passion for transformative roles only add to the anticipation.
Will The Gemini Killer join the ranks of Arthur Mitchell (The Trinity Killer) and other unforgettable foes from Dexter's past? Only time will tell—but the signs are pointing to yes.
