This time I'm going to discuss deleted script and ideas from Wish, however by that I don't mean major plot points such as "evil Amaya" or "humanoid Star", but rather (at least mostly) minor things that have been scrapped from the general plot as we know it.
I'll be using the (digital) graphic novel adaptation for my observations, which I assume is supposed to be similar to the Junior Novelization, albeit maybe a little shortened.
Disclaimer: Any haters in the comments / responses will be blocked!
When it happens: Just after "Welcome to Rosas". The tourists do get food in the movie, but Asha never explains where it comes from.
Why it was deleted: Not sure, maybe because Dahlia is the one whose wish is to be the greatest baker according to what I read (though it's never mentioned in the movie itself and even if it were, no one says multiple people couldn't have the same wish). Then again, it could be just to shorten the movie since it's not significant to the overall plot, only expands upon the idea of granted wishes a bit.
When it happens: Pretty clear from the image, since Gabo does say something similar in the movie. However, the rest of the conversation is not there.
Why it was changed: In this version, it seems no one takes Gabo seriously when he tries to warn about Simon. While it could serve to explain why and how everyone is content with their family / friends losing a part of themselves all around the kingdom (they either make up some excuse for it or simply don't notice at all), it was flipped in the final version so that everyone actually agrees with Gabo. It was probably done to get the audience to better understand Simon's condition and what happens to people after giving their wishes.
(BTW, in the Junior Novelization, Gabo even says that most people become boring following their wish ceremony, maybe it was changed to focus on Simon)
When it happens: Asha does blow flour at Gabo, but Safi's text is not in the movie.
Why it was deleted: In this version, Dahlia can be seen getting the batch of cookies out of the oven, but the teens don't take them. In the final version, this sentence would cause a contradiction, since if Safi can't have Gluten, why was he even going to eat a cookie? Instead, Dahlia warns him it has lemon.
When it happens: Read the scroll's text. In the movie, Asha sees only one reflection.
Why it was changed: I really don't know. It's supposed to hint at Magnifico's fascination with mirrors even before we meet him in order to establish his character, so why change it?
And now there's a big skip, and I'm moving to Act 2:
When it happens: Amaya trying to convince Magnifico to not use the dark magic book.
Why it was deleted: Maybe to make the dialogue consist of shorter sentences for each character in order for the scene to be more flowing and dramatic, and also to show again Magnifico's tragic past and his motives.
When it happens: Asha and Valentino entering the observatory to find her family's wishes.
Why it was deleted: Because it's just a joke that doesn't affect the plot. There's also another joke he says earlier ("Chaos! I love it!") that I didn't include.
When it happens: It's clear from Magnifico's text, but what Simon says is not in the movie.
Why it was deleted: In the movie, he just says "What?" and there's a bit of a focus on his face. I think it's actually enough to hint that he's going to betray Asha, so no need to keep this text. Plus, it actually paints Simon as more loyal to the king from the beginning ("he must really be worried"), as opposed to only after his wish was granted, whereas in the final version he acts purely for selfish reasons.
When it happens: Just after "This is the Thanks I Get".
Why it was deleted: Maybe to finish the song ominously, and for Amaya to not catch him reading the book.
When it happens: Just after Sabino absorbs back his wish, before Magnifico breaks into the house.
Why it was deleted: I'm sure everyone has already seen this deleted scene, and I really don't understand why it was cut at the last minute. Maybe because they didn't have another song for the credits? Also, notice what Sakina says, Sabino completely forgot his talent after giving his wish, I think it's good there's another example of what it does to people in addition to that of Simon, and again, shouldn't have been cut.
When it happens: Just after Magnifico creates his staff. He does have a very similar text in the movie, but doesn't see Amaya's reflection, just notices her behind him.
Why it was changed: Another reference to Magnifico's love for mirrors, we do see his own reflection in the staff, and I'm really not sure why not Amaya's, since that raises the question how he noticed her (his new powers?).
When it happens: Just before Magnifico's second assembly.
Why it was changed: Maybe to save on animation and just show the teens near the stage.
And now I'm reaching the climax of the movie. This was originally a much longer scene that has been changed a lot to get what we have in the final version.
When it happens: After Magnifico traps Star and Asha.
Why it was deleted: I really can't think of any reason for this other than to shorten the movie, which is already very short. It gives us another peek to Magnifico's tragic past, and shows he wanted to capture Star to not only have its power and get rid of what he perceived as a threat to his kingdom, but also because he envied Asha for getting the help he desperately needed when he worked hard for his own wish, which is very understandable, at least for me. It's a real pity this text was cut, I don't get you, Disney!
When it happens: After Magnifico asks Asha how taking her wish into her own hands is working out for her.
Why it was changed: In the movie he just says he doesn't actually care. Maybe they didn't want to show kids how he enjoys torturing and mocking her.
When it happens: After Magnifico sucks Star into his staff.
Why it was deleted: Again, maybe to not show him savoring over Asha's pain. It's a pity because it shows Star was a representation of her wish, so when it was lost, she felt the same pain in her heart as all the other people who got their wishes crushed.
When it happens: Just after the last image.
Why it was deleted: I guess to shorten the movie, making the reference to the "At All Costs" song at the beginning lost...
When it happens: That's Magnifico's response to what Asha says in the last image.
Why it was deleted: For the same reason, though this text seems to be somewhat unrelated. In the Junior Novelization, however, his answer is longer, stating he needed the wishes to feel happiness, which is also a reference to "At All Costs", and now he doesn't need them and the citizens of Rosas anymore, making it a sensible response.
When it happens: Quite clear from the images, but they don't mention Amaya's wish to serve Rosas.
Why it was deleted: According to Disney Wiki and Heroes Wiki, she was formerly a ballerina, i.e the same one we see in the beginning of the movie with Magnifico granting her wish, so it makes sense to remove that.
When it happens: Everyone celebrating their victory.
Why it was deleted: Because that implies Sakina gave her wish only after Asha had been born, which also means the family moved to Rosas not that long ago, but then Sabino wouldn't have waited "decades" for his wish to be granted...
And that's all! There are some other differences I didn't include, but they are not really meaningful in my opinion, just small adaptation changes. Also, since I had started this long post, I finally got the Junior Novelization, and there are more changes there, which I may write another post on.
