I`m on right track with `Avatar` sequels, says James Cameron

Wellington: 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, reportedly.

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."
