From Marvel Studios come three cosmic, action-packed adventures — all to a sonic backdrop of an awesome playlist. In “Guardians of the Galaxy Vol. 1,” brash space adventurer Peter Quill (Chris Pratt) forms an uneasy alliance with a ragtag band of misfits, leading to a battle that will decide the fate of the galaxy. The Guardians must unravel the mystery of Peter’s true parentage, and old foes become new allies in “Guardians of the Galaxy Vol. 2.” And in Vol. 3, Peter must rally his team for a dicey mission to defend the universe — and protect one of their own. Also starring Zoe Saldana, Dave Bautista and Karen Gillan, with the voice talents of Vin Diesel as “Groot” and Bradley Cooper as “Rocket,” all three of these “Guardians” volumes are directed by James Gunn. Volumes 2 and 3 were also written by Gunn, with Volume 1 written by Gunn and Nicole Perlman.
