'Avatar: The Last Airbender 2' director M. Night Shyamalan is set to return for the sequel. Insiders reveal what really went wrong with the first film and explain why the filmmaker is not at fault.

According to Metro.co.uk, a certain production staff who was present behind-the-scenes during the making of the first film claimed that Shyamalan was not completely to blame for the disappointing reception during its 2010 release.

The insider, under the pseudonym Kyatto, took to a forum called Avatar Spirit to relay shocking specifics. He wrote that on top of the horrible budget that left Shyamalan to sacrifice certain elements of the film, there was obvious nepotism during casting which was beyond his control.

Critics and loyal fans alike heavily panned the first installation in the popular animated series by Nickelodeon and put the 'Sixth Sense' director wholly at fault, according to The Geek Lyfe. Even after the film's rendering in 3D, much of the public still displayed disfavor for his alleged interpretation of the series yet despite all these allegations the filmmaker confirmed that he would return to work on a follow-up for the first film.  Shyamalan recently defended his project saying that he only wanted to cater to his young audience and what he believed was the show's target market.

Another article by Movie Pilot reported that there is another side of the preceding film that most of the public could not have been aware of. It was said that Shyamalan received a "horrible budget" and led to numerous adjustments with the huge chunk of it given to post-production for special effects. The director's abilities to helm 'Avatar: The Last Airbender 2' continues to be doubted even at present.

It was also revealed that the whitewashing of the main protagonists was not Shyamalan's decision but was the producers'. The anonymous insider claimed that Nicola Peltz, the young actress who played Katara, was only cast because of "she's the daughter of someone one of the producers owed a favor to as Hollywood loves its nepotism. (Her audition tape was subpar at best)." Noah Ringer, who played Aang, was the only actor who did an honest audition and was chosen for his real talent.

'Avatar: The Last Airbender' 2 is an upcoming fantasy-adventure film - the second in a planned trilogy adapted from the Nickelodeon animated series of the same name. It will be based on the second season (book two) of the television series created by Michael Dante DiMartino and Bryan Konietzko. It remains unclear whether the original cast will be returning to reprise their respective roles for the sequel.
