Dexter Prequel Series Confirmed, Potential for Trinity Killer Spinoff

According to a report by The Wall Street Journal, Showtime is expanding its streaming shows with new spinoffs and a fresh series similar to Homeland. One of the upcoming series is a Dexter spinoff, which will be an origin story of the killer-with-a-conscience portrayed by Michael C. Hall in the original show, which ran from 2006 to 2013 and returned for a one-season revival in 2021 called Dexter: New Blood. The Dexter spinoff will presumably have a new actor play the character. In addition, Showtime is reportedly exploring the possibility of developing spinoffs centered on the backstories of other characters, including the Trinity Killer, portrayed by John Lithgow in the original series.

Showtime executives are working with Dexter showrunner Clyde Phillips on the new Dexter origin story series, which will take place in Miami and “touch on stories of real-life serial killers of the time period,” according to the report. Showtime has also approved a new thriller series, based on the French TV series The Bureau, which will be directed by George Clooney and set within the CIA. Other series in the works include four more shows from the Billions franchise, including a spinoff set in Miami, and other shows with the working titles “Millions” and “Trillions.”
