Marvel Studios has confirmed that the "Guardians of the Galaxy" sequel is the film that it is set to release on July 28th 2017.
The reveal was done by director James Gunn and star Chris Pratt who shot a pre-recorded message for Marvel's Comic Con panel. No further mention was made of "Doctor Strange" or what the studio has planned for all those release dates they've secured in recent weeks.
Earlier during Con, Gunn revealed to Film Divider that he already has several ideas in place for the sequel:
"I know a lot of where I want to go. I have a lot of ideas for stories and characters that are going to appear, and there are documents written up, that some people have, about Peter Quill’s father and his relationship, a lot of stuff about Yondu and a lot of stuff about Drax that nobody knows.
There are a lot of things that are part of the overall schematic that already exist, not to mention a lot of stuff about all of the cultures. There’s a lot of stuff about Xandarian and Kree culture that I’ve written down or I have in my head, as well as Krylorians and Ravagers.
Kevin Feige has stuff. I wrote up a lot. He knows all the stuff and if I died tomorrow they could go make a movie. They could write the story of Peter Quill’s father and it would all be there.
I think Yondu is a very important character, a really important character in this universe, and I think Nebula is really important too and so I think we’ll see more of both of those characters."
Gunn also says he already has a few songs in mind for the next film's "Awesome Mix Tape".
