FIRST LOOK: Zoe Saldana in "Colombiana"

Zoe Saldana is taking a break from playing the peaceful nature-loving Neytiri in Avatar to portray a Colombian badass in the upcoming action flick, Colombiana.

The Part-Dominican, part Boricua actress plays a lethal assassin in the film, which is set in the Americas and due for release in September 2011. Directed by Olivier Megaton (Transporter 3), the photo above shows Saldana in character as Cataleya Restrepo, a young woman who becomes a stone-cold killer after witnessing the brutal murder of her parents at the hands of a Colombian drug lord as a child.

Cat spends her days working as a hitman for her uncle Emilio, a Colombian gangster, but she moonlights as a vigilante hoping to find the man responsible for murdering her parents. Her uncle tries to persuade Cat to leave criminal life, but she’s determined to get revenge.

Saldana, who recently starred in the comedy, The Losers is in big demand in Hollywood these days with lead roles in two movie blockbuster franchises: James Cameron's Avatar, and J.J. Abrams' Star Trek.
