Guitarist Orianthi Panagaris states in an interview that she received an invite to audition for a spot on the tour via MySpace. When she showed up to audition, Jackson and other producers asked her to play the solo from the song "Beat It." After playing the piece, Jackson approached Panagaris, took her arm, and asked if she could play the solo walking across the stage at a specific speed. When she responded she could handle the assignment, Jackson hired her on the spot.
The footage was originally intended for the private library of Michael Jackson. It was also to be used to help the concert's creative team analyze, review and alter aspects of the show before completion.
In 1983, Paul Anka co-wrote with Michael Jackson the song 'I Never Heard', which was retitled and released in 2009 under the name 'This Is It'. This was not noted in the film credits, although it has been confirmed by Anka on ABC's The View (1997).
The blimp in background of the "Smooth Criminal" section says "MJ Air". This was the name given to the airline in the unfinished 3D finale of the concert in which Michael and his dancers would board a plane and take off over the audience.
