Apple Mac laptops feature quite a lot in the film - there is always one next to Michael Bearden's keyboards.
When Kenny Ortega says, "We want some sizzles and some cracks and some pops" for the opening, the clip used is from after Thriller when they are testing out effects.
During the start of The Way You Make Me Feel (with Travis Payne), Michael is wearing a Popeye t-shirt.
During the Dome Project shoot, Michael sucks a red lollipop (most visible in the trailer).
Some observances from the Smooth Criminal vignette! It includes clips from the classic black-and-white films Dead Reckoning, Gilda, In a Lonely Place, Angels with Dirty Faces and The Big Sleep. As he leaves the club (called Break O' Dawn!), he does a body popping move very similar to one at the start of the '88 short film (the part when the music begins from the jukebox). Much of the vignette is quite similar to the original, and the gunfire part appears to be taken from it. When the floodlights lights are suddenly turned on halfway through (just as the man walks shoots the door open, walks through and Michael hides behind the upper window on the roof which he has climbed onto), it looks very similar to around 2:23 in the HIStory album teaser. The blimp behind the cityscape at the end has 'MJ Air' written on - the name of his proposed This Is It ending, with a 3D plane taking off over the audience. Bodydoubles were also used for a few stunts, as well as for other actors from the five movies the vignette uses.
On the making of the Thriller vignette on a framed photo on the haunted house's wall you can see a picture of a a zombie Michael from the original Thriller. After the vignette finishes, on the main backdrop during the performance is stock photo of a graveyard. On the right tombstone it says "Alberto Moreno" - the name of a left-wing Peruvian politician, but the author of the picture.
The mixing with HIStory from They Don't Care About Us is different to the one released just after his death, with more and different camera angles used. Strangely, the added camera angles are unfixed and shakey as opposed to the fixed ones in the original release - but they are HD, have a bigger aspect ratio, rather than SD and window-boxed.
In the original Human Nature rehearsal, when he sings "into the night-time" and the keyboard plays, the camera is on Michael and in the background you can see a cameraman filming the keyboardist. However, in the movie, you see keyboardist playing the section.
You can see scrolling autocues during some songs, most so during the last part of Wanna Be Startin' Somethin' (first half of the song, just before the beatbox and Speechless).
His mic was always on right hand side in previous tours, but it was on his left in This Is It.
