There hasn't been too much news recently for Guardians of the Galaxy. With the movie due out next year, the studio needs to complete the cast. It was reported today that Zoe Saldana is in talks to play Gamora, the deadliest woman in the universe.
This won't be the first time Saldana is playing a deadly character as she is returning to the role of Neytiri in Avatar 2 and also played another comic book character, Aisha, in The Losers. Of course she also plays Uhura in the Star Trek movies.
