MUMBAI: James Cameron is focused on finishing his Avatar novel before starting to work on its sequel.

The director hinted that the final two parts of the planned trilogy could be made into a single film. "We‘re actually talking about that. That‘s not a decision yet," he said. 

"That is something that makes a lot of sense, given the nature of these productions, because we can shoot the entire motion capture and then go back and do cameras over a period of time," Cameron added.

News Corp. chairman and CEO Rupert Murdoch had earlier said that Fox Studio was eyeing a sequel. He later held talks on the same with Cameron about financial and other details.
