I really love the relationship between Ramandu and his daughter. While I won't be bitterly disappointed if he doesn't end up in the movie, I would love it if they included that relationship. Lewis rarely gives parents much of a role in the series(e.g. the Pevensie parents, Eustace's parents, Aravis's parents, even Aslan's father) with the exception of Shasta and his father in the HHB and Tirian and his father in LB. The fact that he includes this lovely father/daughter relationship is quite special then. Again, I won't hate it if he's not in the movie, but they will have missed a chance to put in a refreshing bit of parental love that is so often missing from blockbuster movies these days

I am seriously wondering if there's even going to be a Ramandu himself in the movie.

In light of more recent news:

Lilliandil introduces herself as the daughter of Ramandu.

I wrote in the rumors section.

Well, I just had an interesting thought about Ramandu's presence in the movie. He could actually still be in the movie, but only as a star. If Lilliandil appears as a star and in human form, why not her father just as a star?

I think it the best chance of Ramandu's appearing in VDT! All his daughter has to do is point to the Narnian night sky and say, "There's my dad, twinkling brightly right over there."

(Will Ramandu glow blue too?)

We'll find out December 10th.

On Narnia.com they opened Ramandu’s island, and if you scroll your mouse over to the cave to the right of Edmund it reads:
“Near the edge of the world, old Ramandu watches. How long has he been observing the events of this world, and exactly how far does his gaze extend?”
Does this confirm that Ramandu is for sure in the film?

Highly doubtful.

He may be referenced to in the film by Lilliandil, but I'm pretty sure we would have seen him by now if he was going to be in the movie. I would love to be proven wrong though.

My guess is they will show him briefly as a CGI star/human with only a voice actor (which is the only way I could see them containing his role secret for so long).

If he does appear in human form it would have to be for a very brief, but significant scene that has been kept under wraps from the fans of the film.

Either he will only be mentioned, or he will play a very small part. I can't see them keeping it a secret if he plays a large role- not for this long. At the same time though, we know of his presence since Lilliandil is supposed to mention him, and since you have to click on that thing.

This is so confusing!

This is propbly crazy, but you don’t think they would cast Douglas Gresham as Ramandu do you? As his cameo in the film? it’s a crazy thought, but I thought maybe that’s why they havn’t announced who they cast.

The feeling I am getting from the whole one time they mention Ramandu is that either he only shows up at the end, maybe if they visit RI twice in the movie or if they show the wedding of his daughter and Caspian.

or perhaps they have decided to make Ramandu a star that you can see in the sky. Almost as if he is keeping an eye on his island.

^ That would be an interesting idea. If they cut him out as a character, I hope they reference him like that at least.

It has been confirmed in an interview w/ Mark Johnson that Ramandu will not be appearing in the movie; however it appears he gets a brief mention.

Well although I'd much rather he'd be in the movie...

I hope he's at least mentioned, perhaps he shall be mentioned since he pops up on narnia.com.
