If Ben Barnes doesn't come back as old King Caspian, how about Jeremy Irons? I think he bears some resemblance to Barnes and he is a very excellent actor. Fun fact: Jeremy Irons' nickname is "King".

Louloudi ... Thanks for responding! I can see you have faith in Narnia 4, unlike everybody else.

Jeremy Irons: not a bad choice! He's older, a strong actor, I guess he looks like an older Ben. I'm not too good with resemblances. And the nickname is interesting.

Problem: I want the old King to have a pleasing, soft, gentle face. This is how he came across to me in the book. But Irons doesn't really have that. His face has always seemed too harsh to me. The "soft, gentle face" thing is partly why I picked Plummer and Sutherland, or rather why they came to my mind. I know Sutherland isn't British, but maybe he can pull this off. I wonder if he's ever played a Brit.

I have to admit, it'd be loads of fun to see Ben play old Caspian. I'm not sure he could pull it off, though, especially since he seems to be getting more and more roles...

So I also like Christopher Plummer for the role.

But I always pictured Caspian, even though in his 60's, looking much older. What about Max von Sydow? He's pretty much exactly how I imagined an elderly King Caspian.

I agree ChristProclamer, It would be hilarious to see Ben Barnes as an Old Caspian, but it is very difficult for a young actor to play old. It would be cool if they could get like his father or grandfather to play his older self, which is what they did with Georgie in LWW for the older Lucy. They had her older sister play Lucy. But that's probably not going to happen.

I agree Lilygloves! they could get Ben's father, and even if he's not an actor, since old Caspian doesn't have many lines at all.

I say throw Ben in make up. I think he could pull off Old Caspian. Besides, you guys are right. He IS getting more roles, which could prove helpful for the box office if he gains more fans and then goes back to Narnia. Of course you could have some other big name actor and that would have the same effect. Not that numbers are the most important thing... but they do help

I don't have any suggestions besides aging Ben. I really hate it when they change actors for any reason, but I could understand if they wanted to in this case. Still, anything is possible these days. People can be in movies. Dwarfs, fauns, minotours, centaurs, hags, you name it. So why can't Ben be old?

I agree with AslanIsOnTheMove...make in Barnes. He's getting a whole bunch of different roles now, he's pretty much the jack of all trades, or, dare I say it...Johnny Depp. lol

But yeah, I think he could pull that off, easy.

When I think of him as an Old King Caspian, all I think off are these pictures, probably because he looks kinda pale, and I guess that's what I pictured OKC to look like.

Mr Barnes: If by any small chance you read that ^...sorry, didn't mean to say you looked ill or old. Just my honest opinion.
