Oh Marvel Entertainment, you do seem to have a knack for casting.
Chris Pratt is one example of this. He perfectly encapsulates the cocky and slightly stupid character that is the almighty StarLord. Once you see Pratt in that role it really is hard to even imagine anyone else portraying that character.
Pratt and his amazing castmates, as well as some sharp writing and great direction made Guardians of the Galaxy a huge success, and Marvel will be hoping that Guardians of the Galaxy Volume 2 (which is currently filming at the moment) will be just as big a hit. Director James Gunn does not look like he is going to disappoint either. Gunn recently made a casting decision that, if nothing else, will make a majority of fandom fans insanely happy.
