However many teams of Avengers assemble (the rumour mill says two, both of whom are unable to put their differences aside in Part 1), another group will be joining them. The Defenders - Daredevil, Jessica Jones, Luke Cage, and Iron Fist - will all appear, not a huge shock when their seven year Netflix deals included an option for big screen appearances. Whether they'll be there fighting Thanos alongside The Avengers or protecting the streets of Hell's Kitchen isn't clear, but you have to believe that Marvel are going to make this movie as huge as possible. That will include taking advantage of the popularity of these shows, but one group whose inclusion hasn't been mentioned yet are the Agents of S.H.I.E.L.D.!
