The first character poster for Guardians of the Galaxy is here, and it highlights two of the more unknown characters in the Marvel universe, Groot and Rocket Raccoon. These two are obviously CG creations in the movie and will be voiced by Vin Diesel and Bradley Cooper, respectively.
I still don't really know what to make of this movie coming out- knowing Marvel and the absolute control they have over their properties (especially after ousting Edgar Wright from directing Ant Man, probably due to the uniqueness of a guy like Wright's vision), I sort of suspect this movie won't be all that weird after all, despite the strangeness of the characters. Anything truly off the wall will likely be stamped out by the studio as being too risky. But I guess we'll find out soon enough.
