Update - Goblet of Fire Ultimate Edition IMAX

So, Chloe of Fanedit.org has shared some very good ideas and suggestions, and those in this list are what remain of them that I am implementing for Goblet of Fire - Ultimate Edition.

I am also mentioning new major updates and changes for the opening 15 minutes in a new list below that.

Her Synopsis:

Every time I watch The Goblet of Fire, I have to admit that I feel disappointed. It lacks the mystery and suspense that should be at the heart of the story. As a result, for many people it turned out to be the weakest film in the entire Harry Potter series. Despite high expectations, the film fell short and left audiences feeling underwhelmed. As a die-hard Harry Potter fan, I tried to come up with a list of suggestions to make it the thrilling and suspenseful mystery it was meant to be. With your amazing editing skills, I think the audience will be kept guessing until the very end, never quite sure who is pulling the strings.

Cut completely the dream sequence from the beginning, including the one after the Yule Ball (both will be used later). This way we don’t know what Harry dreamt about, and it leaves the audience with questions. The aim is to keep Voldemort’s plan from being revealed for now, and to keep the audience from seeing Crouch Jr. This means we don’t know who the person walking through the rubble at the championship is, and keeps the air of mystery.

Changes Being Implemented:

Cut the shot of Cedric, his father and Mr. Weasley descending from the sky after using the Portkey.
Cut the shot of the students cheering at the landing of the Beauxbatons carriage that almost swept Hagrid away. That’s something students who like Hagrid would never do.
Cut the scene of the Durmstrang and Beauxbatons students entering the Great Hall. Their entrance/performance never made much sense to me, and the blurry staff thing is ridiculous. We don’t need to see Fleur before she is chosen by the Goblet of Fire. It’s more realistic to have the Goblet choose her as a random student.

(THIS SCENE IS NOT CUT, but HEAVILY altered).

Cut the scene of Karkarov secretly entering the Great Hall entirely. This red herring scene leads nowhere. Also, the film tries too hard to make him a suspect. Karkarov looks suspicious enough with his grimaces alone.
Cut all scenes and shots in which Moody’s eye is watching Harry, including scenes in which he is watching him from a distance (these shots will be used later). This will remove all suspicion from Moody and the audience will never think there is anything suspicious about him.
Change the sound of Moody’s eye. It sounds too electric/mechanical, and electricity isn’t supposed to work at Hogwarts (at least in the books).
Cut the shot of Hermione saying “Your wand, Harry” during the First Task. This makes Harry look more competent, and he wouldn’t be able to hear her anyway.
Cut the shot of Madame Maxime touching Hagrid’s beard. It’s not funny and it’s disgusting.
Cut out all the scenes in which Fleur swims through the seaweed and put them together and insert them before the scene in which Harry swims into the seaweed. It is more suspenseful and exciting in this linear order.
Cut Moody out of the scene where Crouch Sr. talks to Harry after the second task. The idea is to make the audience think that Crouch Sr. is behind everything, which works perfectly with the scene where Sirius speculates that either Crouch Sr. or Karkarov is responsible for Harry’s name being in the Goblet. This would require some heavy editing and appropriate music choices to make it work. Also, the scene in Dumbledore’s office follows immediately after this one, so it would appear that Harry is about to tell Dumbledore that he thinks Crouch Sr. is the villain.
Insert the scene in which Harry finds the body of Crouch Sr. just before the start of the Third Task. This makes it clear to the audience that Crouch Sr. is innocent, and as it is just before the Task, there is no time to wonder who the villain might be. Also, suspicion falls on Karkarov again, as in the previous scene Harry intercepts him and Snape discussing the Dark Mark, and two scenes before the audience learns that Karkarov has been judged by Crouch Sr. (Basically, the order of the scenes is Lake Talk Harry w/Crouch Sr. -> Dumbledore’s Office and Trial -> Snape’s Storage -> Crouch Sr.'s Dead Body -> The Third Task).
When Harry finds out that Snape was a Death Eater, make sure we see Harry’s shocked face at that exact moment, and use something like the sound of drums or some appropriate music. This revelation should be crucial, especially given the HBP, but it’s just mentioned here as if it were nothing.
Crosscut the scene where Harry and Dumbledore are talking about the trial and Harry reveals that he’s been dreaming about Crouch Jr. with Harry’s dream (mostly interior shots) from the beginning. This is where the audience finds out what Harry has been dreaming about and who the man from the championship is. At this point, things start to fall into place, but it is still unclear how Crouch Jr. fits into the plot.
In Harry’s dream, mute the phrase “gather our old comrades…”; this will make the Death Eaters more independent, as in the books, and is consistent with seeing Voldemort in the graveyard for the first time in 13 years. Crouch Jr. also hated the Death Eaters, otherwise he would never have turned Draco, his ‘friend’s’ son, into a ferret
Add an establishing shot after the Snape’s Storage scene, so that it does not feel like the Second and Third Tasks are only a week apart.
Shorten or cut the shot of Moody coming out of the maze and Bewitching Krum (to be used later).
When Harry talks about being in the graveyard before, cut to some outside shots of his dream from the beginning.
Make Voldemort’s eyes red, as in the books, and/or change his voice to make him sound and look even more terrifying. This would make Harry’s PTSD in the OotP more justifiable. Also, in the later films, Voldemort does not seem as scary as he should. (I understand that this is very challenging, and if it couldn’t be done, that’s fine).
Voldemort calls Harry’s mother a “filthy muggle mother” in the graveyard. But she’s not a Muggle. This is a mistake in the film. He should have said ‘Mudblood’ or ‘Muggleborn’ (I don’t know if it can be fixed), (Maybe muting the word ‘Muggle’ would do the trick).
Voldemort tortures Harry with the Crucio Curse in the graveyard. He then lifts the curse by saying Crucio a second time. This makes no sense. Magic doesn’t work that way in the films or the books. I suggest muting the second Crucio.
Intercut shots of Moody stalking Harry throughout the film (including his eye zooming) in the final reveal of who’s really pulling the strings. Also use a shot of Nevil reading the book and the shot (previously cut) of Moody bewitching Krum as he comes out of the maze.
In the scene where Dumbledore says “Your arm, Harry”, mute Harry’s crying. It looks like Dumbledore is hurting Harry, and he would never do that.
Cut the shot of Dumbledore talking about burning the curtains in his fourth year. It’s out of character (at least for his film version) and doesn’t fit the scene at all.
Cut Ron’s farewell to Fleur and Hermione’s to Krum. The end of the film is too long as it is, and Krum says he will write to Hermione, which he never does. It also works better when there isn’t much of a gap between the previous scene, in which Dumbledore tells Harry “You’re not alone”, and the departure, in which the students stand together and say goodbye.
Make all the dream sequences black and white (just an idea, not sure it would work well).

(NOT Black&White, but more horrific).

A few additional tweaks, such as the use of colour grading to make the film more aesthetically pleasing and to maintain the overall gradual darkening of the series, sound mixing to create a more immersive experience for the audience, making them feel like they are truly part of the wizarding world, SFX and VFX here and there, and careful pacing cuts to ensure that the film moves at a steady pace and that the viewing experience is engaging throughout.

OTHER UPDATES AND IMPLEMENTED CCHANGES:

The film opens with new, custom establishing shots of The Burrows (The Weasley’s Home) that set the mood and give time to breath before the introduction of Harry and his friends. Harry is introduced wakening up from a nightmare, but we don’t know what it was about.
Removed a lot of GoF musical scores, replaced SFX and ambience with custom-made, and let the film have a darker, more silent tone in the dark opening minutes. Added Whimsical and Wonderous John Williams when fitting.
The film has insane pace in the opening 15 minutes, and I’ve done a lot of work to create new establishing shots and new close-ups to give the film’s opening time to breathe.
The film has a new Going-To-Hogwarts-By-Train Sequence.
The Great Hall has a completely new structure, with no Filch gimmick and a completely different look and feel. It’s hard to explain, so I’ll release some snippets soon.

… and more.
