Michael C. Hall is returning as the eponymous serial killer in Dexter: Resurrection, and it's set to air in summer 2025. Hall will also provide 'the inner voice of Dexter' narration in the prequel series, Dexter: Original Sin. Dexter originally ran between 2006-2013, and the ending was poorly received by fans and critics alike, which led to a limited series, Dexter: New Blood, arriving in 2021 with a supposedly definitive ending for fans. However, Dexter's return seems to have undone the serial killer's final farewell, and raised the possibility of showrunner, Clyde Phillips, finally getting the opportunity to use the alternate ending he intended for the original series.
