Like most on-screen heroes, the initial design for Sister Night went through some noticeable changes before HBO's live-action follow-up to Alan Moore and Dave Gibbons' seminal comic book series Watchmen hit the airwaves back in October.During an interview with Variety, Watchmen star Regina King -- who played masked police detective Angela Abar/Sister Night -- and some of the show's costume designers reminisced about the process that went into crafting the outfits worn by its characters. "When I received the script, there was a letter in the script," King recalled, explaining she couldn't wait to open it. "And there's an artist rendering of Sister Night with my face. I mean, I just got chills, just again, going back to that moment." While Sister Night's final costume clearly took inspiration from Christian nuns, the concept design revealed during the interview is even more overt with its religious imagery.RELATED: Watchmen Star Regina King Says She'll Only Return if Lindelof Does

Elsewhere in the interview, costume designer Sharen Davis discussed the yellow masks worn by police officers in Watchmen's universe. "That was the yellow that [showrunner Damon Lindelof] wanted," she said. "But the hardest part was to find the yellow that we really liked. That took about three or four weeks. Davis explained that the team behind the show wanted the color of the masks to convey "a really strong presence."

Finally, fellow costume designer Meghan Kasperlik spoke to how informative being involved with the show is, specifically referring to its portrayal of the 1921 Black Wall Street Massacre in Tulsa. "I had a phenomenal time working on the series," she said. "It was very eye-opening. I was not aware of the Black Wall Street history. So, it was really lovely to be able to create the story that was telling something that has happened in history to show the rest of America."
