Here's the email I received about the Avatar 3D re-release.
On August 27, return to Pandora and re-experience James Cameron's History-Making Epic film, with more than Eight Minutes of Never Before Seen Footage- exclusively in Digital 3D and IMAX® 3D. Since - and largely as of result of - AVATAR's release last December, the number of available digital 3D screens has exploded, and moviegoers who missed experiencing the film in 3D, as well as fans that want to return to Pandora again, will now have that opportunity.
The Oscar® and Golden Globe® winning epic is the highest grossing film of all time, taking in over $2.7 billion in worldwide box office. It is also the top-selling Blu-ray disc of all time.
