Zoe Saldana has suggested that the two Avatar sequels will be filmed simultaneously.

The actress, who played Neytiri in the first instalment of the James Cameron movie franchise, said that filming the second and third movies needed to happen "at the same time".

Speaking on tonight's (May 4) The Jonathan Ross Show on UTV to promote the Star Trek Into Darkness film, she said: "I think that they're doing a part two and a part three and they're probably going to shoot it at the same time.

"Because if we just do two and then wait, I'll probably be 45 or 50 by the time we get to part three. It takes a long time, it's a very hard process."

Saldana also confirmed that shoot will begin early next year. It was recently revealed that the first sequel to the 2009 movie won't be released until at least 2015.
