Main Cast of Dexter: Original Sin & Their Roles
The highly anticipated prequel Cast of Dexter: Original Sin brings a fresh yet familiar cast to portray younger versions of iconic characters. Here’s a closer look at the actors stepping into these pivotal roles:
Patrick Gibson as Dexter Morgan
Patrick Gibson plays a young Dexter Morgan, long before he became the infamous Bay Harbor Butcher. This version of Dexter is still discovering his dark urges while working as a forensic intern at Miami Metro Police Department. Gibson, known for his roles in Shadow and Bone and The OA, brings a layered performance to show Dexter’s transformation into a methodical serial killer who follows the Code of Harry.
Christian Slater as Harry Morgan
Christian Slater takes on the role of Harry Morgan, Dexter’s adoptive father, and a respected Miami Metro homicide detective. A crucial figure in Dexter’s life, Harry teaches him the moral code that helps him control his homicidal urges—only targeting criminals who escape justice. Slater, a seasoned actor from Mr. Robot and True Romance, brings gravitas and intensity to this legendary character.
Molly Brown as Debra Morgan
Molly Brown steps into the shoes of Debra Morgan, Dexter’s younger sister, known for her bold and outspoken personality. As a teenager in this prequel, Debra idolizes her father and dreams of joining the police force, unaware of Dexter’s dark secret. Brown, previously seen in Senior Year and The Marvelous Mrs. Maisel, captures Debra’s rebellious yet vulnerable nature.
Christina Milian as María LaGuerta
Christina Milian portrays a young María LaGuerta, an ambitious detective striving to make her mark in a male-dominated police department. Fans of the original Dexter will remember LaGuerta as a high-ranking officer, but in Original Sin, she’s still fighting for recognition. Milian, famous for her work in Love Don’t Cost a Thing and Be Cool, brings charisma and determination to the role.
James Martinez as Angel Batista
James Martinez plays Angel Batista, a detective who works alongside Harry Morgan. Batista is known for his loyalty, humor, and strong moral compass, characteristics that Martinez, recognized from Love, Victor, and House of Cards, authentically portrays.
Alex Shimizu as Vince Masuka
Alex Shimizu takes on the role of Vince Masuka, a rising forensic expert with a sharp mind and an even sharper wit. Fans of Dexter will remember Masuka’s often inappropriate sense of humor, and in Original Sin, we see his early career unfold. Shimizu, seen in Blue Bloods and The Blacklist, brings comedic timing and intelligence to this fan-favorite character.
Reno Wilson as Bobby Watt
Reno Wilson plays Bobby Watt, Harry Morgan’s trusted police partner. Though not part of the original Dexter series, Watt’s character adds depth to Harry’s backstory, potentially influencing Dexter’s upbringing. Wilson, known for Mike & Molly and Transformers, provides a strong presence as a dedicated officer.
Patrick Dempsey as Aaron Spencer
Patrick Dempsey joins the cast as Aaron Spencer, the captain of Miami Metro’s homicide division. As Harry Morgan’s superior, Spencer plays a key role in shaping the police culture that Dexter grows up around. Dempsey, best known for Grey’s Anatomy and Enchanted, lends his authority and charm to this pivotal role.
Michael C. Hall as the Narrator (Dexter’s Inner Voice)
The original Dexter, Michael C. Hall, returns as the narrator, serving as Dexter’s inner monologue. His voice provides insight into Dexter’s evolving mindset, bridging the gap between the prequel and the original series. Fans will appreciate Hall’s return, maintaining the essence of the beloved character.

Sarah Michelle Gellar as Tanya Martin (Chief of Forensics)
One of the biggest surprises in Dexter: Original Sin is the addition of Sarah Michelle Gellar as Tanya Martin, the chief of forensics at Miami Metro and Dexter’s direct boss. Unlike his later mentor Vince Masuka, Tanya is sharp, no-nonsense, and expects excellence from her team. Gellar, famous for Buffy the Vampire Slayer and Cruel Intentions, adds star power to the cast, making Tanya a character to watch.
