The first full trailer for Dexter: Original Sin has been released and it teases the set-up for the prequel series. Based on the early years of Michael C. Hall's serial killer, it follows him as a young man starting out on his murderous journey.
The younger version is played by Patrick Gibson, but his inner voice sees Hall return to his iconic role. And now, fans are convinced he may be back in an even bigger capacity too. This stems from the opening of the new trailer, which begins where the original show ended: with Dexter bleeding out in the snow.
