Did James Cameron accidentally pen 5th 'Avatar' movie?

Washington:James Cameron may have accidentally already written the 5th installment of 'Avatar.'

The 60-year-old film maker, who's aiming to create an Avatar cinematic universe, has been working with his writers on what has become 3 sequels, and while 1st new installment has since been pushed to a 2017 release date, it seems in the midst of all of that he somehow wrote 5th film, the Verge reported.

Composer James Horner, who's worked with Cameron on films like Titanic, said that Cameron already had 4 sequel s which he was trying to turn into 3, and was sure the director would figure out a way to do so.

If it all works out, the final ' Avatar' film could be in theatres by 2019.
