I'm sure we all remember the scene where Katy was crying backstage and nearly cancelled her concert (all I wanted to do during that scene was enter the screen and give Katy a big hug and tell her everything will be ok, and that I'm there for her if she needs a friend to talk to). It was then followed by concert scenes where it showed her (understandably so) struggling to sing "Not like the Movies" (and I truly admire her for her bravery for even attempting that song, given how hard it must have been). From what I read, it seems that the backstage scenes were in Brazil. However, I found a review of her Brazil concert, and it said that she sang "Not Like the Movies" beautifully, and that it was the highlight of the concert. It did mention her crying during "Thinking of You", but the person who wrote the review thought that was a positive, since it seemed that she was very emotionally into the song (he obviously did not know what was going on backstage).
Because of that review, I assume the concert scenes were not from Brazil. From what I read, most of the concert scenes were shot in LA on 11/23/11. However, I also found reviews of that concert, also saying she sang beautifully.
My question is, when and where was that scene where she struggled to sing "Not Like the Movies". I assume it was not the same night as the backstage scenes.
