Gamora made her first appearance in the Marvel comic books in 1975. The green-skinned assassin is the last of a race that was wiped out by the Baldoon. She is the adopted daughter of the villain Thanos, who made his presence known during the end credit scene in Marvel's The Avengers.
Gamora's powers include super-human strength, agility, and healing abilities.
It should be noted that Zoe Saldana's deal is not finalized yet. We reported in February that Jason Momoa was in talks to play Drax the Destroyer, before negotiations broke down a month later, causing Marvel to go with Dave Bautista, who has since been confirmed.
James Gunn is directing from his own screenplay. Production is scheduled to begin this June.
Guardians of the Galaxy comes to theaters August 1st, 2014 and stars Chris Pratt, Dave Bautista, Zoe Saldana, Michael Rooker, Ophelia Lovibond, Lee Pace, Glenn Close, Karen Gillan. The film is directed by James Gunn.
