The Defenders are coming to Netflix. And now we know when! The premiere streaming service has unveiled the first-ever teaser trailer for their next Marvel adventure, a limited series that brings all four of their previous standalone series together. Yes, The Defenders have united in Hell's Kitchen, and now we have a first look.

Netflix released this mysterious trailer online. It's titled 'Midland Circle Security Elevator B', and it clearly shows all four of our heroes riding in a freight elevator to destinations unknown. Here, we see Daredevil, Luke Cage, Iron Fist and Jessica Jones together all at once as the Hell's Kitchen Avengers, and it's marvelous!

If you watch closely, you'll notice that the time stamp on the security camera goes out right at 08:18:20:17 after Jessica hits it. And thus, we have a premiere date folks! Yes, The Defenders will be making their way to small screens around the world on August 18, 2017. You can see this entire scenerio play out in the video below, courtesy of Netflix.

This security camera footage matches up with a scene that was previously teased when the first promo photos from the show arrived. All of these heroes, at this point, aren't quite familiar with each other, but they do know each other's handiwork. The as-yet formed team all arrive at Midland Circle of their own volition, not expecting to find the others there. This is leading to what has become known as the signature 'hallway' battle that has been a running motif throughout each individual series. Only this promises to be the biggest, grandest hallway fight scene filmed yet.

The Defenders cast includes the Netflix all-stars. Charlie Cox returns as Matt Murdock/Daredevil alongside Krysten Ritter as Jessica Jones, Mike Colter as Luke Cage and Finn Jones as Danny Rand/Iron Fist. Also appearing from the various series are Elden Henson, who will be reprising as Foggy Nelson along with Deborah Ann Woll as Karen Page, Eka Darville as Malcolm, Carrie-Anne Moss as Jeri Hogarth, Scott Glenn as Stick, Jessica Henwick as Colleen Wing, Elodie Yung as Elektra, Rachael Taylor as Trish Walker, Simone Missick as Misty Knight, and Rosario Dawson as Claire Temple.

Some suspect that Jon Bernthal's Punisher will also be stopping by for at least one episode, even though he was busy shooting his own standalone series for Netflix as The Defenders was in production. Sigourney Weaver is playing the main villain, a character called Alexandra.

Marvel's Daredevil co-showrunner Marco Ramirez is serving as showrunner and executive producer for the series alongside Drew Goddard, Jeph Loeb and Jim Chory. Director S.J. Clarkson (Marvel's Jessica Jones, Dexter) directs the first two episodes of the mini-series event.

Marvel and Netflix have also debuted a new viral site called NY Bulletin, which seems to still be under construction. We do get a gallery of NY Bulletin covers, which you can check out below the teaser. Consisting of 8 episodes, The Defenders promises to bring summer to a close in high fashion. Take a look at the first footage.
