Netflix kicked off the first of its four Marvel superhero shows with Marvel's Daredevil earlier this year, and production is already under way on Season 2. Marvel's Jessica Jones is up next, and while Marvel and Netflix haven't announced a premiere date yet, executive producer Jeph Loeb offered some interesting new details during the TCA press tour, revealing that the show is more of a psychological thriller than a superhero series.

"When we first sat down and started talking about Daredevil, what we said was, for all intents and purposes, it was a crime drama first and a superhero show second. One of the things we've talked a lot about is that Jessica is in many ways a psychological thriller first and then a superhero show second."

The series is based on the comic book series entitled Alias, written by Brian Bendis, which spanned 28 issues between 2001 and 2004, and followed Jessica Jones (Krysten Ritter) as a retired superhero who becomes a private investigator. The comics were published under the Marvel Max banner, which featured comics with more explicit content such as graphic sex and violence. We don't know yet how R-rated the show will be for Netflix subscribers, but we do know who the main villain will be, David Tennant's Kilgrave, a.k.a. The Purple Man. Jeph Loeb revealed that Kilgrave will have a villainous arc similar to Vincent D'Onofrio's Kingpin in Marvel's Daredevil.

"In the same kind of way Vincent D'Onofrio owned his half of Daredevil, you'll see David Tennant own his half of Jessica Jones. What you get out of Jessica is a sort of hold-your-breath tension as to what's going to happen. When you see the dynamic between Krysten Ritter and David Tennant... that question of 'What's going to happen next?' and 'What could happen next?' and how that's driven by character is something that is so important to not just the scripts but also the way the show is shot, and the way that everyone reacts, and the way those two react with each other."

It isn't known how faithful the show plans on being to the comic, especially since Kilgrave doesn't become a key player until later on in the comic book run. It's certainly possible that the show could come up with a different back story for The Purple Man, but we won't know until the show premieres later this year. Executive producer Melissa Rosenberg also spoke about how Jessica stands out from Marvel's other heroes.

"Jessica is about paying rent, getting the next client. She's dealing with a fairly dark past. She's trying to get through the day. She's not really trying to save the city, she's trying to save her apartment. At her core, she wants to do something good. She wants to contribute to the world. But there are a lot of personality issues for her that can get in the way...Jessica Jones is a brawler. She gets drunk, she gets pissed off, and boom, you're down. She doesn't wear a costume, she doesn't have a mask. She's just who she is."

After Marvel's Jessica Jones debuts, Netflix will debut Marvel's Luke Cage and Marvel's Iron Fist in 2016, with all four characters coming together to form The Defenders, sometime in 2017. Luke Cage will be portrayed by Mike Colter, but Marvel and Netflix still haven't cast Iron Fist yet. What do you think about these new details?
