Marvel's GUARDIANS OF THE GALAXY May Be Helmed By James Gunn
It's also an indication that GUARDIANS OF THE GALAXY could go a bit darker than the other Marvel movies. Completely an assumption though.
Of course Joss Whedon probably has had a big hand in the selection of Gunn as they have similar traits in filmmaking.
Keep in mind that this is yet another ensemble film and so is extremely difficult to shoot effectively. So many dynamics and you have to build all those characters to some level of appreciation too. Top that with the fact that the GUARDIANS characters are going to need a lot of work for suspension of disbelief. Not to worry though, Marvel has shown an amazing tenacity in making that facet work with previous efforts.
Can't wait for this! And the probable appearance of THANOS too, pre - AVENGERS 2.
