CB: Meet Gamora, the deadliest woman in the galaxy. She's beautiful, lethal and heading straight for a theater near you on August 1. Played by Zoe Saldana in Marvel's Guardians of the Galaxy, Gamora is a trained assassin and the last of her species. She also has personal ties to the supervillain Thanos, which tends to complicate things when she teams up with the awesomely heroic Guardians. She may be smiling on the exclusive character poster below, but don't let that smile fool ya--this is one dangerous lady.
