There are a few things we don’t know regarding the versions. We do know that theatrically there was the 35 mm version (the camera prints), the digital version (no copy exists), and the IMAX version (no copy exits, though many related what they noticed was missing). We do know that from the 35 mm to the DVD several things were changed and then more changes for the BR (none for the D+ version have been noted). It is possible that the DVD version was the original digital cinema version and it is possible some changes were made and they are different. We’d need to uncover the digital version to be sure. Until we have something more concrete, we can assume there were up to 5 versions, but definitely 4 that we can document.
