Other mistake: During one of the recording studio scenes, there's a short segment that shows a bunch of VU (audio level) meters close up. The very first meter in that sequence is not a VU meter. Its from of an old HF (High Frequency) Amateur Radio transceiver; The scale is marked for RF, SWR, and ALC. I'm suspecting that someone involved with the post production editing is a Ham.
Other mistake: When Pumba is singing and they show him as a baby warthog farting in the water killing the butterfly, it is actually a baby Red River hog that is portrayed.
Other mistake: The scene after Genie saves Aladdin from drowning, Aladdin is recovering. The left pocket of his pants has a clear outline of a smartphone in it, or possibly a radio mic.
Other mistake: When Jack and Rocky get on Ed Sheeran's plane, they are carrying 2 guitars. After the Moscow concert, before the 'song challenge', Ed says Jack wrote 'Back in the USSR' on a 3 hr plane flight with no guitar on the way to the show. (00:37:38 - 00:38:38)
Other mistake: Whenever a cat puts a hat on, there are no cuts for the ears to pop through. Instead, the ears simply swap from being on the cat to being on the hat between frames. Sometimes, when the cat's head is a bit too high, the ears on the hat are sometimes slightly misplaced.
