In Marvel Studios’ “Guardians of the Galaxy Vol. 3” our beloved band of misfits are settling into life on Knowhere. But it isn’t long before their lives are upended by the echoes of Rocket’s turbulent past. Peter Quill, still reeling from the loss of Gamora, must rally his team around him on a dangerous mission to save Rocket’s life—a mission that, if not completed successfully, could quite possibly lead to the end of the Guardians as we know them. James Gunn writes and directs “Guardians of the Galaxy Vol. 3,” which stars Chris Pratt, Zoe Saldana, Dave Bautista, Karen Gillan, Pom Klementieff, featuring Vin Diesel as Groot, Bradley Cooper as Rocket, Sean Gunn, Chukwudi Iwuji, Will Poulter and Maria Bakalova.
