At the time of its release, this production employed the greatest number of 3D cameras ever used for a single project -- and in fact utilized every digital 3D camera and recording deck in existence at the time.
Previously, the lyrics in "Pride (In the Name of Love)" have set MLK's death as "Early morning, April 4." In the movie Bono sings "Early evening, April 4" correcting the historical error in the original recording.
As of 2010, this film has not been released to home video. U2 (and their label, Universal Music Group) retains the ancillary rights to the film, and is withholding this film from the market until such time as consumer 3D technology has "caught up" and is capable of showing the film as it was originally intended.
Because this film was captured in high-definition video, with effectively two frames per "3D frame", each frame was nearly 20 megabytes in size. The entire film occupied nearly a petabyte of storage (approximately 10 to the 15th bytes, or 1,000,000GB).
Firsts: following post-production, this film became the first live-action 3D film to be screened at the Cannes Film Festival; the first live-action film to be shot, posted, and exhibited entirely in 3D; the first live-action digital 3D film; and the first 3D concert film.
This film was edited together from seven Latin American concerts (mostly in Buenos Aires) and two shows in Australia, plus a special "phantom shoot" 10-song set performed without an audience to capture close-ups. In addition, some footage was included from a "test" filming that was done in Mexico City (for example, the scene where Bono reaches out to the camera during "Sunday Bloody Sunday"), which was primarily done for the camera crew to learn the show choreography, but was not intended for final use.
A theatrical re-release was done in March 2009 to coincide with the release of U2's new album, 'No Line on the Horizon'. In addition, the film was shown in a single IMAX showing at a U2 academic conference in October 2009; the Rock and Roll Hall of Fame celebrated the opening of its new by showing the film through January 2010; and the Academy of Motion Picture Arts and Sciences held a screening at their 3D film conference in July 2010.
