CBR has an
interview with James Gunn for GotGv2.
Highlights:
*A bit in the vein of the first movie, a bit different
*Casting is almost done, shooting starts in February, will last 10 months
*At least one new character. Won't say who or how many.
*Nebula is important
*Stan Lee will be in it
*GotGv2 is stand-alone, not "about" leading up to anything
*Won't comment on Adam Warlock, but seemed to imply Warlock may be important in Infinity War
*GotG will probably continue if v2 does well.
*Other Marvel "cosmic" properties he's interested in, but Marvel will shoot him if he says too much
*He'll likely only be working on GotG-related projects
*No Earthlings but Quill
*Drax doesn't like Baby Groot (official confirmation of "Baby Groot" terminology?)
*Rocket's about late-20s in age (if he were human)
He also has a couple comments on Civil War and Captain Marvel, which I posted to the corresponding threads. Bringing up Infinity War and Adam Warlock together is interesting, though, especially with the wording he used. He seems to be hinting that Warlock may appear in GotGv2, which will be the teaser for Infinity Wars (though there's still 3 movies between them), maybe?
