Fast foward to 2015; I'm at Denver Comic Con with The Hubs and browsing the 50% graphic novel area. I devour Marvel's Secret Invasion, the story arc that comes after Civil War and where Jessica Jones is featured a bit more. Turns out, she has superpowers herself. Going back further, the comic series Alias, which ran from 2001-2004 is all about her as a private investigator, investigating other superheroes.
Here's that fantabulous announcement clip/teaser. Take note of the creepy voice whispering 'Jessica'. That's David Tennant, who's playing the main antagonist, The Purple Man.
