James Cameron, the director of the Academy award winning film "Avatar" said in an interview that the release of the highly-anticipated sequel of his film will be rescheduled to 2017 due to some unforeseen setbacks. Cameron, who also directed "Titanic", said that he is currently working on three "Avatar" scripts.

The release of the sequel for "Avatar" was originally scheduled for 2016, but according to Cameron the story that he is writing right now has become very complex that he needs more time to finish the script.

In an interview, Cameron said "There's a layer of complexity in getting the story to work as a saga across three films that you don't get when you're making a stand-alone film." He also added that "We're writing three simultaneously and we've done that so that everything tracks throughout the three films. We're not just going to do one and then make up another one and another after that. And parallel with that, we're doing all the design. So we've designed all the creatures and the environment."

Right now Cameron is heading the writing team and aims to finish the script by the end of the month in order for the film production to start.

To date, "Avatar" holds the record for the highest grossing film of all time with a worldwide gross of $2.79 billion. Next is "Titanic" which grossed $2.19 billion worldwide, the film was also directed by Cameron. "Avatar" was nominated for nine Academy Awards including Best Picture and Best Director award; it won the award for Cinematography, Art Direction and Visual Effects. "Titanic" on the other hand was nominated for a record 14 Academy Awards and won 11 including the Best Picture and Best Director award. "Titanic" holds the record for most awards won by a single film, a record it shares with "Ben Hur".
