The San Diego Comic-Con is underway, and Netflix kicked things off with a few announcements about its various Marvel superhero series. Luke Cage is due September 30th, and its teaser trailer brings about a minute and a half of Mike Colter fighting bad guys in hallways. The Iron Fist series' release date is still TBA, but its trailer showed off a hint of what's to come there as well. Last but not least the preview for The Defenders leaves much more to the imagination but lets us know that as originally promised, Cage, Jessica Jones, Daredevil and Iron Fist will team up to take on bad guys in 2017. Speaking of Daredevil, Netflix also confirmed that the Hell's Kitchen hero will get a third season which is "coming soon" -- check out all the videos below.
