Okay here's my list.

1. Turn the movie into an action film rather than one about discovery and adventure.

2. Mess with the spiritual themes that are found in the book.

3. Changing the purpose of the voyage.

Besides the ones that FriendofNarnia2 mentioned. I am worried they will leave out the part where Lucy gives into the temptation to say the eavesdropping spell.
P.S. My first post on the new NarniaWeb.

Like FriendofNarnia2, I'm just hoping they don't change the initial purpose of the voyage. I'm hoping Doug Gresham will do his job of keeping the right focus.

My greatest fear? The domino effect! It happened in PC. They made so many "necessary" changes. I hope the changes and/or additions to the movie don't cause a whole slew of bad changes.
It's kind of funny, we fear change so much (and rightly so) but I wonder if anyone consider changes/additions a good thing? What if they change something that actually adds the the theme of the book?

....ROFLOL, like that would happen. Hollywood's not that good at stuff like that. I'm starting to get concerned they're adding unnecessary battles, but still being optimistic about this one.

One of my fears is that part from the synopsis about them facing dragons (!).

And I really, really, REALLY want to see the final of the story just like it is. I'm a little concerned about this. Maybe they'll change that key quote "I have another name" into something more subtle.

I fear that they'll add tension or arguments between Caspian and the Pevensies like PC...I don't know about Eustace. The only time they argue majorly is when Caspian wants to go to Aslan's country. I agree with you twinimage.

Most of the big fears i had regarding changes have already been confirmed, or near-confirmed, as going ahead - Creatures on the Crew, Added Battles, and Added Plot (unfathomable fate etc).

One of the few remaining fears i have is that they will mess with the distinct character-like qualities of the individual islands, by messing about with the order and/or combining/removing some. I could tolerate a certain amount of rejigging the order, but combining/removing islands would be an "unfathomable" disaster in my opinion.

Fears:
- Humor, jokes and wisecracks;
- Battles or romance inserted where they don't exist;
- Purpose of the journey is changed.

I'm afraid of them having Edmund not be excited to go back to Narnia. I'm also hoping they don't have any added tension between Caspian and Edmond. Then also I'm afraid of the general plot getting twisted into some formulaic action/fantasy rather than in ways that enhance the story. For example if Ramandu's daugther has to be rescued from something, or if they insert a villain who chases them from island to island, that would be depending too much on what has been done in the past rather than what will work here.

I think my fears are the same as all of ya'lls. I saw on another Narnia forum where someone said they hoped Edmund would'nt have any romance. I hope they don't have Caspian and Edmund fall in love with Ramandu's Daughter and get mad at each other or something.

Laura! How could you even think such thoughts! Caspian and Edmund fighting over Raman - oh I can't even bring myself to say it. That has to be the worst thing someone has mentioned yet. The scary thing is I wouldn't put it past them doing something like that.

1. Adding more action sequences
2. Adding a rivalry that is not mentioned in the book
3. Adding a romance that is not mentioned in the book
4. Changing the reason for the voyage
5. Changing things to make it more of a Hollywood production
6. Losing the episodic feel
7. As less references to pirates of the Caribbean as possible
(I've got nothing against pirates of the Caribbean, but that's not the way they should make a narnia movie)

i'm a bit concerned about the added "pitched battles" mostly because there is a lot going on in VDT already. to keep adding more stuff might unnecessarily take time away from other adventures and/or unnecessarily complicate the storyline.

i understand completely about making for interesting storytelling, specially this is a film medium where plot and characters have to be streamlined otherwise you confuse your general audience. i'm not for "dumbing down" the story, just dont overdo it either way.

if the added battles makes certain storypoints more compelling or emphasizes a lesson, like the slave trade or something, then by all means go ahead.

and at the risk of sounding shallow, but i really want Eustace the Dragon to look soooo good. i'm a big dragon fan, so i'm really looking forward to what the dragon would look like.

I really hope they keep the end of the book, with the lamb and all of its symbolism, in the movie. I also hope that they keep each of the islands. My greatest fear is that they will delete those parts, because they are big themes of the book!

Another important part of the movie that I would like not to be changed too much is when Aslan removes Eustace's dragon scales. That scene has always been one of my favorite parts of the series!
