The premiere season of "Jessica Jones" has officially begun streaming on Netflix, and showrunner Melissa Rosenberg already has plans for season two. What's more, she says there's a possibility for that before "The Defenders" makes it to the small screen.

"We might be able to do a second season of 'Jessica Jones' before 'The Defenders,'" Rosenberg told Variety. "I think they are working that out now. It might not be possible from a logistical standpoint, so we don't know just yet. And of course they haven't given us a second season, though I am ready to dive in if they do. Throughout the first season, as we were breaking the story, so many ideas were coming up. For season two, the idea was to leave a lot of storytelling doors open and to have avenues to pursue for many years after this season. We leave this season not necessarily on a cliffhanger, but there is a big change in Jessica's circumstances."

Though we don't know what Rosenberg is referring to by Jessica's "big change" quite yet, it's worth pointing out that Jess is revealed to be pregnant with Luke Cage's child at the end of Brian Michael Bendis and Michael Gaydos' "Alias" series, on which the series is based.

David Tennant, who stars in the show as Zebediah Kilgrave, also opened up on his experience playing a Marvel villain, what Kilgrave's background is like and whether or not he'd like to return for an "Avengers" movie.

"I think there's something rather chilling about him," Tennant explained to Vanity Fair. "He's not particularly interested in world domination, or accruing vast amounts of wealth, or destroying the Fantastic Four, or whatever it might be. He's just out to get what he can and he has this extraordinary ability which means that he has a certain indestructibility, really."

"At first he comes off as all bad, and he pretty much is, but you can at least understand some of the reasons why he might be. He's more interesting than just a mustache-twirling villain... I think there are -- how do you call it --clutches of contradictions in Kilgrave's character," he added.

"There's an acceptance that we are in the same world as the Avengers and Spider-Man," he continued, "but you can't quite imagine it happening. Having said that, I'd be very happy to be in an 'Avengers' movie. Any of them."

"Jessica Jones" stars Krysten Ritter, David Tennant, Mike Colter, Rachel Taylor, Carrie-Ann Moss, Eka Darville, Erin Moriarty, Wil Traval and Susie Abromeit. It is rated TV-MA. Season 1 is now streaming on Netflix.
