Patrick Dempsey Joins ‘Dexter: Original Sin’ In Series Regular Role

Patrick Dempsey (Grey’s Anatomy) has joined the cast of Paramount+ with Showtime’s Dexter: Original Sin in a series regular role. In the Dexter prequel series, Dempsey will play Aaron Spencer, the Captain of the Miami Metro Homicide department who has a decades-long relationship with Harry Morgan (Christian Slater).

Dexter: Original Sin stars Patrick Gibson, who is taking over the titular serial killer role (in his younger years) made famous by Michael C. Hall in the Showtime mothership series. Molly Brown, James Martinez, Christina Milian and Alex Shimizu also star. Production is underway in Miami with Clyde Phillips at the helm.

The 10-episode original drama series follows Dexter in 1991 Miami, a student transitioning into a serial killer in training. When his bloodthirsty urges can no longer be ignored, Dexter finds solace and understanding in Harry. As his only confidant, Harry teaches Dexter a code that’s designed to help him find and kill people who deserve to die — all while avoiding getting caught by law enforcement. This is a particular challenge for young Dexter as he begins a forensics internship at the Miami Metro Police Department.

“Patrick Dempsey is a beloved actor who is internationally known for the iconic characters he has played and his performances,” said Chris McCarthy, Paramount Global co-CEO and President/CEO, Showtime & MTV Entertainment Studios. “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 executive produced by Phillips and produced by Showtime Studios and Counterpart Studios. Scott Reynolds also EPs alongside Hall, Mary Leah Sutton, Tony Hernandez and Lilly Burns, with Robert Lloyd Lewis producing. Michael Lehmann will serve as directing executive producer.

Dempsey is best known for his portrayal of Dr. Derek Shepherd on the ABC series Grey’s Anatomy, which earned him a SAG Award and multiple Golden Globe nominations. He is also known for starring in classic ‘80s films such as Can’t Buy Me Love and Loverboy.

Dempsey can most recently be seen in Michael Mann’s Ferrari in which he portrays Piero Taruffi opposite Adam Driver. Before that, he starred in Eli Roth’s horror film Thanksgiving and the Disney+ film Disenchanted. Additional credits include Bridget Jones’s Baby, Transformers: Dark of the Moon, Valentine’s Day, Made of Honor and Enchanted.

He is repped by UTA, Burstein Company, and Goodman, Genow, Schenkman.
