If a deal is made, Saldana would join Chris Pratt, who is playing Star-Lord, and Dave Bautista, who's portraying Drax the Destroyer, in the space-set adventure movie. The superhero group also includes Groot, a giant tree-man, and Rocket Raccoon, a genetically engineered animal with a knack for guns and explosives.

James Gunn is directing the movie, which is eyeing a June production start date. Disney has set an Aug. 1, 2014, release date for Guardians.

Saldana already has plenty of space (and tentpole) experience. She reprises her role as Uhura in Star Trek Into Darkness, which opens May 17, and will step back into her alien skin of Neytiri for Avatar 2.

Saldana, repped by ICM Partners and Morris Yorn, also stars with Christian Bale in the recently wrapped crime drama Out of the Furnace.
