I liked the river scene, and they needed it too show that Peter didn't want to kill the wolves, not uyntil he was sure that he had too. I think this really builds up his character and makes a needed precursor for the time when he does kill Maugrim.

As for Susan not blowing her horn, the movie makers probably just didn't think about it, although all the previous explanations make sense. I especially agree with her forgetting it, I know I could easily forget it in a time like that especially if I just got it. You know since we are asking this question, we could why she didn't use it at the stone table, or when they had to warn the narnians of the Aslan's death and the White Wtches approach insted of using the trees? Just thought I'd throw that out there

I think the reason Susan didn't use her horn was because Peter was there. In the scene where she DOES blow the horn, Peter wasn't there.
I do think this is the way the director/whoever imagined it to be.

And as a side note, what is so wrong with the waterfall scene? I was talking to someone on another website about the scene, and we basically agreed that the scene was good because although it wasn't in the book, it didn't add much to the storyline. And it was pretty cool all the same.

What was wrong with it? Cheesy dialogue. A lame attempt to make us think Lucy was dead. Susan acting like an idiot. Peter's clueless attempts to aim his sword like a gun. The pathetic behavior of the wolves. The ridiculous way they escaped the wolves. Miraculous lack of hypothermia. Basically it was a great big epic fail.

^^ sorry you feel that way, Bookwyrm!

I love the Frozen River scene! the reason Peter was not so good with his sword is simple: he was scared and he'd never used a sword before! not to mention that he's got three people yelling three different peices of advice at him!

OK, I just watched it. I still don't think it's a bad scene. It sure beats a "danger-less" journey to Aslan's How, because it's kind of the climax with the wolves (at least on the trip).

I don't think the dialogue is too cheesy either. Looking at it one way, one might think of Susan as being a coward, and maybe rightly. But driven by fear, who knows what they might do? In panic, one might think that giving themselves up would make the enemy have mercy, or some such silly thing.

Lucy's disappearance is a little lame, I'll admit. I would rate it right up there with

(Warning: Lord of the Rings The Two Towers movie 'spoiler' below)

One of the older Pevensies should have seen that happen. Lucy would scream or something to let them know, she wouldn't just let go and float away!

As for Peter with his sword -- if I were holding a sword and a wolf was advancing on me and my siblings, I would hold it like a gun too. At this moment, Peter's not a hero. These are 3 children. They are not specially brave or equipped in some way others aren't (unless you count Father Christmas's gifts, but I think you get what I'm saying).

To redirect more towards the title of this thread: I just don't think Susan thought of using the horn, as I said before.

^^ yes, I will admit, Lucy disapearing was kind of lame. but it's the only part I don't like.....it makes the drama (I LOVE drama) so much better! I think this sequence really helped the plot......
