Actor Tim Blake Nelson -- known for his roles in The Incredible Hulk and O Brother, Where Art Thou? -- has revealed his role in HBO's upcoming Watchmen series.

"My character’s name is Looking Glass, and it’s a really interesting, intriguing character," he told the Empire Film Podcast. "I don’t really completely understand him, and that’s intentional. Damon Lindelof metes out facts about your character as you go along... So I’m learning as I go along who this guy is, and trying to... It’s almost like fresco painting. The clay is always wet.”

Nelson also addressed the show's approach to its source material. “Damon Lindelof... is doing something that I think Alan Moore actually will appreciate, which is that he's treating the Watchmen novel as a history book, and he's imagining the world created by the Watchmen now," he said. "And he's using that as a prism through which to examine a lot of issues currently on the surface of American culture and politics."

The article also revealed the reported casting call for Nelson's character, describing him as “a good looking cop, the native Oklahoman isn't simple as his rural accent makes him appear to be. A top interrogator and behavioral scientist, he may also be a bit of a sociopath.”

Looking Glass does not seem to be a character from Alan Moore and Dave Gibbons' original comic of the same name. As the series is set after the conclusion of the graphic novel's story, adding in new characters makes sense.
