Phase 3 of the Marvel Cinematic Universe will begin in May with the highly anticipated Captain America: Civil War. It will continue in November, expanding Marvel's cosmic side with the introduction of Stephen Strange to the MCU in Doctor Strange, and in 2017 we will reunite with Marvel's space misfits in Guardians of the Galaxy Vol. 2.
Writer and director James Gunn is currently in Atlanta working on pre-production of the Guardians sequel, which will once more bring together Star-Lord (Chris Pratt), Gamora (Zoe Saldana), Rocket Raccoon (voiced by Bradley Cooper), Drax (Dave Bautista), and Groot (voiced by Vin Diesel). Gunn is not the only one already hard at work; Saldana is also starting to prepare for her transformation into Gamora.
Saldana shared a photo on her Twitter account showing a small part of the process of becoming Gamora. In the picture, we can see Saldana's face and neck being covered in a green-colored substance used to create facial casts; these are so the special effects make up team can build the subtle prosthetics needed for Gamora's face.

Gamora is the last of her species, the Zen-Whoberis, who were exterminated by the Badoon – a reptilian alien species, older than the Kree. She received treatments from her adoptive father Thanos, enhancing her speed, strength, agility, and durability, all in an attempt to turn her into a weapon. With her ability in martial arts, Gamora gained the nickname "the deadliest woman in the whole galaxy."
Plot details are being kept under wraps, but what we do know about Guardians of the Galaxy Vol. 2, is that it will be a story about fathers, introducing us to Peter Quill's dad – and no, it's not J'Son of Spartax, as in the comics, and it's not Mar-Vell either, as rumoured earlier this week. Michael Rooker's Yondu, Sean Gunn's Kraglin and Karen Gillan's Nebula will be back and the team will meet a new member, rumoured to be Mantis.
Guardians of the Galaxy Vol. 2 is scheduled to start shooting in February, meaning we will have to wait until then to get an official synopsis as well as a cast confirmation. In the meantime, we can keep re-watching Guardians of the Galaxy in hopes of catching the “Easter egg everyone has missed” and which James Gunn has stated won't reveal until, maybe, after Guardians 2 comes out.
