All 5 Actors Who Played Harrison Morgan

After Dexter Morgan’s son, Harrison, was born in Dexter season 4, the character saw several casting changes within the franchise as he grew older. Since debuting in the original series as an infant to becoming one of Dexter: Resurrection‘s main characters as an adult, multiple actors have had the opportunity to portray the titular serial killer’s child.

Though contradictions with Harrison’s exact age in the series timeline have been debated, each new era in his adolescence has seen a recast. When he was supposedly three or four years old in 2013’s Dexter season 8, Harrison’s new actor became Jadon Wells, who was actually a few years older. Harrison then returned as a 16-year-old in New Blood‘s 2021–2022 sequel series, this time played by Jack Alcott, who maintains the role today.

While Jack Alcott and Jadon Wells’ iterations of Harrison Morgan are the most notable given the elevated nature of his role in the story, there was a long line of actors who came before them. When accounting for his appearances in infancy, seasons as a growing toddler, dream sequences, and Dexter‘s sequel shows, there are more actors who have played Harrison than one might think.

Various Child Actors Play Baby Harrison

Dexter Season 4

Several uncredited infants play Harrison Morgan in Dexter season 4. Harrison is introduced to drive the relationship between Dexter and Rita forward as a couple. They find much-needed peace in suburban Miami with Rita’s two other children, Astor and Cody, until John Lithgow’s unforgettable Trinity Killer brutally kills Rita.

It wasn’t until Dexter season 5 that audiences get to see an actor consistently play the part of Harrison. Up until that point, seemingly interchangeable babies played the part.

Evan George & Luke Andrew Kruntchev Play Infant Harrison

Dexter Seasons 5-7

The first two actors officially portraying Harrison Morgan in the original series are twins named Evan George and Luke Andrew Kruntchev. These two toddlers played the part between Dexter seasons 5 and 7. Much like the way Mary-Kate and Ashley Olsen were cast as Michelle in ABC’s Full House, Harrison was played by two young actors who were interchanged throughout those episodes.

Due to child labor laws, this allowed the showrunners to consistently shoot more often and for more hours than they would’ve been able to had they only used a single actor. It is unclear why the Kruntchev twins left the show after the seventh season wrapped, but there are rumors that it was because of their role on Days of Our Lives.

Lucas Adams Played Future Harrison In Dexter’s Vision

Dexter Season 7

Lucas Adams was cast to play Harrison Morgan in a short dream sequence in Dexter season 7, wherein an idyllic Harrison is shown while Dexter imagines his life with Hannah McKay in the future. Adams was not officially cast to play the part other than in Dexter’s imagination, as he was meant to be portraying the character about a decade after that point in the timeline.

Other than his short stint on Dexter, Adams had a part in the soap opera The Young and the Restless early in his career. He would have been too old in 2021 to be cast as the teenage Harrison in New Blood, so the actor wouldn’t have been eligible for the part even if Showtime wanted to bring him back.

Jadon Wells Played Four-Year-Old Harrison

Dexter Season 8

In Dexter season 8, six-year-old Jadon Wells assumed the part of four-year-old Harrison Morgan. There was a noticeably stark and obvious difference between the actors in season 7 and 8, but casting Wells resulted in a much more expressive Harrison Morgan. Even though his tenure on the show lasted only one season, Wells did a wonderful job at playing Harrison and contributing to the complicated Morgan family dynamic.

Wells played the part until Dexter‘s original series finale, but ultimately didn’t reprise his role as Harrison Morgan in Dexter: New Blood or its successor, Resurrection. Much like the Kruntchev twins, Wells also had a part in Days of Our Lives after his time on Dexter came to an end.

Jack Alcott Plays Teenage/Adult Harrison In Dexter’s Sequel Shows

Dexter: New Blood & Dexter: Resurrection

Jack Alcott officially became the new Harrison Morgan in Dexter: New Blood. When Alcott auditioned and was first cast, he was told he’d be playing a character named Randall, who was described as having a close relationship with Dexter and a significant character arc during New Blood. Until he had signed an NDA and received the first script for the show, Alcott had no idea that he would be playing Dexter’s teenage son, Harrison (via Gold Derby/YouTube).

The 2021–2022 limited series saw Harrison track down Dexter and reunite with him after Hannah mysteriously passed away in New Blood, just a few years after Dexter abandoned them. Alcott’s arc as teenage Harrison in New Blood saw him contend with the reality of his father’s abandonment, the truth about his father being a serial killer, and looking inward at his own darkness that had been festering over the years – wondering whether he was going to turn out like Dexter.

Jack Alcott does a great job portraying Harrison’s contentious relationship with his father, as he delicately balances his deep emotions along with the sense of abandonment he gains from an absentee father. Harrison’s journey throughout Dexter: New Blood is a rocky one: while he initially rebuffs Dexter, there’s a clear need for him to be accepted. New Blood needed the right actor to compellingly convey these complex conflicts, and found the right star in Alcott.

His moral dilemmas in New Blood culminated in Harrison shooting Dexter in the chest in the finale, which was originally thought to indicate the death of Dexter and potentially the franchise at large. However, Showtime eventually walked back that ending and revived the titular killer in 2025, revealing Dexter secretly survived the gunshot wound before tracking down his son in New York City in Dexter: Resurrection.

While New Blood‘s finale is certainly controversial among audiences, Jack Alcott was praised heavily for his portrayal of the serial killer’s son. As such, it’s no surprise that the actor was tapped to reprise his role as Harrison Morgan in Dexter: Resurrection, which sees him now as a young adult rejecting his dark urges while fixing his relationship with Dexter.

How Watching Harrison Grow Up Through Different Actors Made His Journey More Powerful

Harrison Morgan’s Fate

It’s unknown if Harrison Morgan’s arc was set from his infancy, but watching the character grow up through different actors has made his journey more powerful. Viewers didn’t get to see Harrison through his later childhood and early teenage years, but that doesn’t mean that Dexter fans didn’t see Dexter’s son grow up.

When Harrison is first introduced in Dexter season 4, he’s a typical baby, but his presence raises a very important question in people’s minds: will he inherit Dexter’s killer urges? More simply, are killers born or are they made? Harrison complicates Dexter’s life and his murders as time marches forward, and the serial killer must learn how to balance his family and his extracurricular activities.

The first major Harrison Morgan actor change occurs after the Trinity Killer murders Rita Morgan and makes sure that the baby is born in blood, the same as his father. While the switch-up is clearly due to needing an older actor for the role of Harrison, it does point to a very specific change in the character as a whole. Harrison was then recast again in season 8, as a more expressive actor was needed to show the child’s maturity.

The teenage/adult Harrison shows up in Dexter: New Blood and Resurrection, which showcases how much he has grown and contended with his own Dark Passenger in Dexter’s absence. Watching Harrison from infancy to his morally complex adult self is necessary for Dexter, and it makes his journey more powerful and disturbing. Using child actors ultimately makes his arc more real and the consequences more terrifying.
