Considering that it took the overwhelming majority of the first season just for Matt Murdock to get his classic suit, it was pretty obvious that Marvel had plans for Daredevil to get a second season.
That has now been confirmed with a teaser trailer that shows literally zero new content; instead, it remixes scenes from the past season into a pastiche that simultaneously reminds viewers why they liked the show in the first place while enticing a potential new audience into giving the show a chance.
One of Daredevil/Matt Murdock's more unique traits is his devout Catholicism, and the style of the teaser brings that home, taking still images from the first season and redoing them in classic Catholic iconography—the images are painted all over the walls and ceiling of a church that's reminiscent of the Sistine Chapel. As the camera pans and pulls back to show more of the images, the audio also touches on the theme of religion as some of Matt's discussions with his priest play over the scene.
This seems to suggest that our titular hero's moral struggles with cleaning up Hell's Kitchen are far from over, particularly when you consider that Frank Castle (aka The Punisher, to be played by The Walking Dead's Jon Bernthal) will be bringing his particular brand of justice to the city. Elektra Natchios (played by French actress Elodie Yung) will also be thrown into the mix, making for an interesting dynamic: neither she nor Castle believes as strongly as Charlie Cox's Murdock in the preciousness of life.
It all seems to be building towards a showdown of the multiple facets of Murdock's thinking and morality: as a superhero, as a friend, and as a lawyer. It doesn't sound like this season will have any direct connections to the eventual foursome show The Defenders (comprised of Daredevil, Jessica Jones, Luke Cage, and the yet-to-be-met Iron Fist), but with it being this early, and the teaser giving us so little information, it's really impossible to know just how tied in this second season of Daredevil is going to be with the Netflix side of the MCU. What we do know is that whatever Matt does, he's definitely going to feel bad about it.
The second season of Daredevil will be released on Netflix worldwide on March 18 of this year. It is almost guaranteed that we'll be getting plenty of teasing info about the show over the next couple of months.
