Zoe Saldana and Sam Worthington have signed up to star in another three Avatar movies.
The two stars played lovers in the James Cameron blockbuster and now they'll be back for the moviemaker's back-to-back sequels.
They will join Stephen Lang, who will reprise his Colonel Quaritch in the new movies even though the marine character was killed in the original film.
The first sequel will reportedly hit cinemas in December, 2016.
Avatar is the highest-grossing movie in film history.
