His admiration for the show was so strong that when the opportunity arose to express his fandom to Dexter himself, he couldn't resist. Meeting Michael C. Hall at Comic-Con was a moment he cherished. "When I met Michael C. Hall at Comic-Con, I had to say, 'Thank you for being so great,'" Slater recalls.
He believes that Harry was a very interesting character in Dexter, and this prequel series offered an opportunity to explore him further. "I definitely felt like Harry was a very interesting character that you only got to see glimpses of [in Dexter]. So this was an opportunity to explore that character some more and see the challenges that he went through in his younger days, and the mistakes that he made and the traumas that he suffered. And I think all of those things kind of added up to a lot of the decisions and choices that he makes with his son later."
"It's important," Phillips told PEOPLE at the show's premiere in New York City on Wednesday, Dec. 11. "It's important to me creatively. It's important to me as his friend. And it's important because I know the impact it will have on the audience."
Recalling Hall's appearance at Comic-Con in San Diego in July, Phillips said that the fans' response to Hall's involvement really sealed the deal for him on the prequel. "We were sitting with Christian Slater, Molly Brown and Patrick Gibson and then Michael walked out with a box of doughnuts like from the OG show and the place went crazy."
Dexter: Original Sins premieres Friday, Dec. 13 on Paramount+ with SHOWTIME Plan.
