The planned second season of the ‘Dexter’ prequel series ‘Dexter: Original Sin’ has been canceled.

Deadline reports that despite Showtime’s renewal announcement in April, the decision was reversed. The show had originally debuted in December 2024 and wrapped up its first and only season in February. The network’s parent company Paramount recently merged with Skydance, which may explain why the prequel series was canceled.

‘Dexter: Original Sin’ was set in 1990s Miami and starred Patrick Gibson as a younger version of the titular serial killer, with Christian Slater portraying his police detective father, Harry.

The news comes as sequel series, Dexter: Resurrection, starring Michael C. Hall, is winding down its first season on Showtime and Paramount+. That show is expected to return for a second season.
