“Patrick Dempsey is a beloved actor who is internationally known for the iconic characters he has played and his performances,” said Paramount Global Co-CEO and President/CEO, Showtime & MTV Entertainment Studios Chris McCarthy in a statement. “We are thrilled to have him join our all-star cast of Dexter: Original Sin, the highly anticipated origin story of the franchise.”

Dexter: Original Sin is set in 1991 Miami, 15 years before the original series, as Dexter “transitions from student to avenging serial killer,” according to the official synopsis. “When his bloodthirsty urges can’t be ignored any longer, Dexter must learn to channel his inner darkness. With the guidance of his father, Harry, 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.”

Other previously announced cast members include Patrick Gibson (Shadow & Bone) as Dexter Morgan, Molly Brown (Billions) as Debra Morgan, James Martinez (Love, Victor) as Angel Batista, Christina Milian (Grandfathered) as Maria LaGuerta, Alex Shimizu (The Blacklist) as Vince Masuka and Reno Wilson (Good Girls) as Bobby Watt.

Dexter vet Clyde Phillips will serve as showrunner and executive producer. Michael C. Hall, who famously portrayed the titular character for eight seasons plus the sequel series Dexter: New Blood, will also executive-produce.
