Sam Worthington and Zoe Saldana have officially signed on for all three Avatar sequels, joining Stephen Lang.
THR reports the actors have finalized their deals, and that the three films will be filmed by James Cameron back-to-back-to-back.
Cameron released the following statement: "Jake Sully is a rare combination of passion, strength, street smarts and soul, which requires a lot from an actor. Sam brought to the role a combination of sensitivity, vulnerability and strength. Zoe captured every aspect of the character I envisioned, bringing to Neytiri a mix of delicacy, fierceness and incredible physicality. I am beyond pleased they'll be returning with us to Pandora."
Zoe Saldana is starring in Guardians of the Galaxy this Summer for Marvel Studios which hits August 1st.
With Saldana signing on Avatar for the long haul, will she be back for a Guardians of the Galaxy sequel?
For a comparison, reportedly Martin Freeman filmed The Hobbit trilogy over two-and-half years.
The first sequel to Avatar gets released in December 2016, with the second to in December 2017 and the third a year later in December of 2018.
