If you found any mistakes with the movie post it here! I only found one BIG mistake, in certain windows on the night shots there is green light comming through the window, they must have forgot to add in the night sky. S o if you have found anything else post it here!

One thing that annoyed me when I first saw it, and still now, is there is a couple of bad editing jobs. The first is when Harry and Dudley are in the tunnle with the dementor and Harry goes,"Dudly, Run!". If you look carefully you'll see that there is a bit missing as dudley moves to run away: one second he is leaning againt the wall and the next he is runing away.
The other one is when Umbridge (sp?) is fixing some tea in her office and she stirs it, and lifts it up a bit adn then, suddenly, she is taking a sip. It may have been intentional but I am not sure.

Hmm.... i have never noticed that i am watching it now as i am typing, ill have to look for the mistakes. I have found another on, when Neville is in the hall of prophecies he casts petrificus totalus at barty crouch jr but it never shows the spell hitting him and barty junior falling it just shows neville saying the spell and barty already on the floor frozen. I think that they are forgetting to add extra parts to the final scene.

Barty junior??? When is Barty Junior in OOTP?

Anyway, moving on:

The one mistake I spotted was when they find the shelves in the Hall of prophesies, and Neville is standing directly below the Harry/Voldemort prophesy. Bearing in mind Neville is actually quite a bit taller than Harry, he is looking up at the prophesy. When Harry goes to take it down off the shelf, all of a sudden it's at a level with Harry's head. So it must have moved down several shelves in the time it took Harry to walk over to the shelf from when Neville first brought its existence to his attention. Very poor continuity if you ask me.

Oh, I never noticed there were mistakes! Actually, I never thought there might be mistakes, in such a greatest movie.
By the way, Barty Crouch's there? Are you serious?
I think I'm gonna watch the movie again, just as to find them

ha ha Barty Crouch?? I thought he was dead! I always try to look for mistakes and stuff, but never really found any. But what people posted here is interesting so I'll have a look!

Barty Crouch was supposed to be killed (or be kissed by a dementor; same differance really) but I it wasn't included in the 4th movie so I guess they just brought him back as a deatheater (which really makes no sence because he was at hogwarts when the 4th movie ended.)

It would make sense if he was part of the breakout from Azkaban (don't forget - that's where DD would have sent him back to at the end of the film GoF). But I don't think he did feature in the film OotP. I'll check the credits. Back in a mo...

No, unlike the discussion that was going on re Lavender Brown being cast as black in POA (and she was actually named as Lavender Brown) - Barty Crouch Junior is not credited in OotP. So all we have are various death eaters, but no one specifically named as Barty Crouch Junior. Here's a link to the full list of credits on IMdB.

There is one thing I noticed about this movie that just really confused and annoyed me. During some of the DA practice sessions, a few students are heard saying "Levicorpus"! How would they know about this spell if HBP the movie hasn't come out yet?! Seems a pretty important mistake...

EDIT: I realised that there is a whole thread dedicated to this topic right after i posted. Sorry everyone!
