James Cameron is reported to be overseeing the final film of the 'Terminator' series, acting as something of a godfather to in-talks director Tim Miller. So far, details are vague as to whether the upcoming film will mark a re-boot of the story, or merely act as a concluding paragraph in a long saga.

James CameronJames Cameron to oversee final 'Terminator' installment?

The filmmaker who first created the sci-fi franchise will take back some rights to his beloved series in 2019, which means he may have a certain degree of control over how the story will end - or, indeed, how it will be re-told. He is rumoured to be working with Tim Miller who directed 'Deadpool'.

The series first began with 1984's 'The Terminator' starring Arnold Schwarzenegger. Cameron returned for 'Terminator 2: Judgment Day' in 1991, but stepped away from the project for 'Terminator 3: Rise of the Machines' in 2003 and 'Terminator Salvation' in 2009, as well as the TV series 'The Sarah Connor Chronicles'. While he wasn't credited on the most recent installment - 2015's 'Terminator: Genisys' - he was something of a consultant to the writers and producers on the storyline.

Cameron will be taking back many of the rights to the story, most of which are held by Skydance's David Ellison after he acquired them from his sister Megan Ellison in 2013. But, due to laws regarding copyright reversion, Cameron will ultimately become the beneficiary of future adaptations.

The filmmaker has a lot under his belt before 2019, however. He's got potentially four more 'Avatar' scripts to write, the second of which is due to be released next year, as well as Japanese manga adaptation 'Alita: Battle Angel', an animated feature based on the 'Terminator' franchise, and he's directing a thriller entitled 'The Informationist' as well as the documentary 'The Last Train from Hiroshima: The Survivors Look Back'.
