The "AVATAR: SPECIAL EDITION" is set for release in cinemas on August 26, exclusively in Digital 3D and IMAX 3D, according to Twentieth Century Fox and James Cameron.

The "Secial Edition" of Cameron's box office hit film will include more than eight minutes of new, never-before-seen footage. The original release of Avatar in December 2009 raked in over $2.7 billion at the global box office and had a huge following around the world.

"Audiences repeatedly told me they wanted more of Pandora, and wished they could have stayed there longer. So we're making that possible. 'AVATAR: SPECIAL EDITION' will be exclusively in 3D, and will have eight minutes of never before seen footage, including new creatures and action scenes," Cameron told the media.

"You'll be seeing it like never before."

The Oscar and Golden Globe winning epic Avatar is the highest grossing film of all time, earning over $2.7 billion in worldwide box office. It is also the number 1 Blu-ray disc of all time in terms of sales.

In the film Director James Cameron gives audiences a spectacular world beyond imagination, where a reluctant hero takes on a journey of redemption and discovery as he leads a heroic battle to save a civilisation.
