Wellington, Aug 11 : James Cameron feels he's on the "right track" with ' Avatar' sequels, which he calls as the "mega project," as he's almost done with the scripts and the preliminary preparations.

The 59-year-old Oscar-winning ' Titanic ' director, said that he was working on the fantasy film's 2nd, 3rd and 4th follow-ups all at once and they were all coming together as he's totally devoted to them, Stuff. co. nz reported.

Cameron added that though he was working on the sequels together, they would be released a year apart from each other in 2016, 2017 and 2018, so that the audience remember them as "one big story." (ANI)
