Meet the cast of Dexter: Original Sin
Some of the original Dexter cast members are appearing as their younger selves in Original Sin.
After the original run of Dexter and then the release of spin-off series, New Blood, Dexter fans will now be pleased to learn that Original Sin has now landed on our screens, bringing the titular serial killer's origin story to life.
Set in 1991, we follow Dexter as a student who then quickly turns to a life of killing as he learns to channel his "inner darkness", according to the synopsis.
It continues: "With the guidance of his father, Harry (Slater), he adopts a Code designed to help him find and kill people who deserve to be eliminated from society without getting on law enforcements’ radar. This is a particular challenge for young Dexter as he begins a forensics internship at the Miami Metro Police Department."
Original Dexter star Michael C Hall may not wholly be reprising his leading role but he does return as Dexter's inner voice in Original Sin, with Irish actor Patrick Gibson (Shadow and Bone) taking the lead.
Speaking about his initial reservations with the role, Gibson admitted to The Hollywood Reporter: "I was worried about the idea of a prequel, but then I read it and was like, 'Oh, no – this is sharp.'"
Gibson's joined by plenty of recognisable faces in the new series, who bring to life younger versions of some original Dexter cast members. But who's who in Dexter: Original Sin? Read on to find out.

Patrick Gibson as Dexter Morgan
Who is Dexter Morgan? In this prequel series, we follow Dexter on the unlikely path from being a student to a serial killer. As he begins a forensics internship at the Miami Metro Police Department, though, he must balance that challenge with killing those that he feels deserve to be eliminated from society.
Speaking about taking over the iconic role from Michael C Hall, Gibson said (via The Hollywood Reporter): "I’m not sure if I’m fully prepared for this because I don’t know what’s to come, but I know that once it’s out in the world, it doesn’t really have anything to do with me anymore. I’m hoping I can bring some of myself to this character while also honouring what he did."
