OK, I'm going to make this really complicated. According to the book, the Dawn Treader lands at all of these islands before finding the three kids:

Galma
Terebinthia
Seven Isles
Brenn

I don't know if any of those are really big to the story because they're just mentioned at the beginning when Drinian is talking.

Here's the list of the 7 they go to after finding Lucy, Edmund, and Eustace:

Lone Islands
Dragon Island
Burnt Island
Deathwater Island
Dufflepud Island
Dark Island
Ramandu's Island

OK, I'm starting to wonder just what happened. We know from what we've seen that there should be the Lone Islands, Dragon Island, Dufflepud Island, and Ramandu's Island. That's 4, meaning Deathwater Island, Dark Island, and Burnt Island remain. So two of these must have gotten cut.

Interesting. We know they hired an actor to play Lord Rhoop, Bruce Spence. So that tells me that the Dark Island should be there as well.

Therefore, I can see Burnt Island being totally dropped and Deathwater Island being combined with Dragon Island as the most likely one.

We will know for sure in a tad under 12 months from now. But in the meantime there will be some speculation about this. (Especially in this thread.)

I'm going with dropping Burnt Island as well. I can't wrap my mind around what other islands could be dropped or consolidated...as long as they don't cut the events of the Deathwater chapter completely. It's one of my favorites.

Well, dropping Burnt Island, or merging that in with Dragon Island is totally fine with me, its the kind of thing you can often accidentally skim over if you are reading the book fast, and in terms of its major plot points they are all connected with Dragon Island anyway.... As for the others though, i am very unhappy about that.

I often mentioned it in the past how it would annoy me no end if they even considered merging islands together. To me the islands aren't just incidental locations to facilitate a little bit more plot, they are unique characters in their own rights. Each has its own particular style, themes and characteristics. "Consolidating" 7 islands into 5 is almost as bad as if they had "consolidated" 4 Pevensies into 2 in LWW. Maybe they did feel it was necessary for the purposes of streamlining the story, but in my opinion its one of those things you just have to deal with when you are making a Dawn Treader movie.

Hopefully further developments on this will come along and maybe relieve my fears in some way that it is not as bad as i think (i could easily tolerate two islands being situated right next to each other if they wanted to have the events of one occurring at the same time as the events of another, just as long as the islands were still two distinct and unique places) but for now im going to be in a bad mood about this for a while. hmph.

I've known about one island getting cut/merged/whatever for some time. Obviously I can't say which one on pain of death and the destruction of NarniaWeb But I didn't know about a second island. I'll be curious to see if Ernie says which ones. I doubt he will... probably too early for that.

Lady Galadriel, your list is very good I agree that we'll be seeing the Lone Islands, the Island of the Voices (Dufflepuds), and Ramandu's Island for sure. But I haven't seen any proof of Dragon Island yet... oh we know that Eustace gets turned into one at some point, but we also know that two of those other islands have to-be-discovered Lords. AT LEAST one of those will be cut.

And while I have the opportunity and since I finally get a chance to rant publicly, I would just like to say that this is the exact kind of thing that makes me sooo irritated about the Narnia movies so far. The apparent need to add in stupid plot points (unfathomable fate) at the cost of removing or minimizing parts of the book that people love (removing islands) is ridiculous. I was pretty lenient with Prince Caspian because I felt that they probably couldn't make a literal adaptation because of how weird the timeline of the book is, but I am going to be returning to my hard-core fandom for the remainder of the books to movies. I at least shall be difficult to impress... unneeded changes like this aren't going to help.

But in all fairness, I'm going to wait and see before giving my final judgement... who knows, it may be extremely cool and I won't miss any islands at all.

I definitely think it's likely they have cut Burnt Island. I also think that rather than another island being cut, it has been combined with another island.

Here's a few combinations they may try, none of which are very appealing to me.

Deathwater Island and Dark Island
Dragon Island and Deathwater Island
Dragon Island and Dark Island

Some of those islands would require some major changes to the story as well as characteristics about the island themselves, but I could see them doing something like this.

I personally wouldn't be surprised if they the deathly golden pool as a body of water located somewhere on Dragon island.

I am not really surprised. It is very much a wait-and-see sort of thing for me.

I personally wouldn't be surprised if they the deathly golden pool as a body of water located somewhere on Dragon island.

Nor would I be surprised at something like this. Knowing we are losing a few island stops in the movie, consolidating some events on other islands along with the visit to Dragon Island may be workable.

My gut feeling tells me Dragon Island is going to be a setting for quite a bit.

Well, unless we count that one picture of what could have been a treasure for evidence of Dragon Island, although I don't think that was confirmed.... I would imagine that if Eustace gets turned into a dragon, though, chances are there is Dragon Island. How else would he get turned into a dragon? Although you do have me wondering....

I almost wonder if they may drop Deathwater Island and then add Lord Restimar to the sleeping lords at the end, or else drop Dark Island and add Lord Rhoop to the sleeping lords. It would certainly be simpler and easier for people who do not know the story to follow if Lord Rhoop was already one of the sleeping lords (because in the book he joins them).

*musing* Considering that nothing happens on Dark Island really except for them getting frightened and meeting one of the lords... I wonder if that would look so good on film. Meaning, they may either play it up (but I don't know if they can do that while staying in a PG rating?) or cut it altogether.

I always thought Burnt Island would be cut and/or combined with Dragon Island because the only thing that happens there is Reepicheep claims the coracle.
The only other combination that really makes any sense whatsoever to me would be Dragon and Deathwater. But I really don't like that idea.
Lady Galadriel! Don't even suggest such a thing!

Burnt Island can be easily cut or combined without much fuss. I hate to see them change anything but if they had to cut an island, I would go with Burnt Island. There's not much that goes on there.

My feelings exaclty. I am so wondering about this unfathomable fate, and they haven't peeped a bit. This really makes me think this is their "own" idea, not really even "inspired by" Lewis. Humph.

Yeah, I think Burnt Island is definitely out. It's so small. My guess would be the Deathwater/Dragon Island mix. That would really take out a lot of the gravity of the greed though, because it would then show the reformation of Eustace and also (some) of the failings of Caspian/Edmund, which would not be a good pairing to me. However, it would make sense for a dragon to settle around a gold pool. If these two are mixed, I wonder if they will find the pool while Eustace is dragoned (while looking for him) or later after he's been un-dragoned.

I'm not so sure about deleting two islands out of the seven, but I suppose packing the experiences of whatever two into the others wouldn't be so bad. As long as the plot didn't become too complicated for people to understand. For example if they did have Caspian and Edmund discovering the "Deathwater" and fighting over their authority whilst the crew was still in search for Eustace...it could be hard to follow.
Burnt Island is a very good possibility for an omition, but I really can't see how they could take out any others just because the experiences on each island are unique to that island. Trying to make them happen somewhere else is a difficult task. Everything else sounds great plot-wise excluding the "Unfathomable fate." That makes the waiting even harder to bear when we don't know about what will probably turn out to be one of the key factors.

I think there is a decent possibility that Burnt Island has not been cut.

First of all, I think that if Burnt Island wasn't in the film, Ernie wouldn't have even bothered to mention it as one of the islands. I think he would have just said we consolidated 6 islands into 5. It's such a small island in the book, that most people readers don't even realize it exists anyway.

Secondly, if I remember correctly, the book mentions that the island may have at one point been inhabited by people, but was destroyed by something, (perhaps a dragon). I could see them using this island as an excuse to further their "unfathomable fate" plot point.

Perhaps Burnt Island is still inhabited by people. We know that the MLG is around for the dragon attack, so perhaps her character arc ends on Burnt Island. (That way she doesn't have to come along for the remaining portion of the voyage.)

Seven is a cooler number than five, but I can see the need for consolidation- the movie needs to be around two hours long after all.

That said, I really hope they've combined Deathwater and Burnt Island with Dragon Island.
If they cut out, say, Dark and Burnt Islands on the basis that they weren't inherent to the plot or didn't show much of the characters' personalities I would be very disappointed.
I am very excited about seeing Dark Island onscreen and I hope it somehow stays in.
