It will be interesting to see who they will get to do the score for Narnia films or series. I have a lot of respect for Harry Gregson Williams who did it for the first two Walden movies. I don't think it's likely he's going to do it again.

I suppose Hans Zimmerman could do it. Yet, he's so well know. He's done music for The Lion King, The Dark Knight Trilogy, Inception.. the list goes on.

I also thought of Howard Shore, who did it for The Lord of the Rings Trilogy and The Hobbit Trilogy. Though I don't know how he could manage to do a Middle Earth sound and a Narnia sound.

I also thought of Roque Banos, who did the music for In The Heart of the Sea. The music is actually beautiful.

So I think it will be interesting to see who they will get to do the score for Narnia films or series.

My answer for this question is always Bear McCreary. Most of his work is TV, but he's also done movies and video games in a lot of different genres. He's incredibly versatile and each soundtrack he composes is unique. Compare his work on Black Sails, Outlander, and Battlestar Galactica to get a good idea of his range.

And for a slightly out of left field suggestion, I'm a big fan of Austin Wintory's work. He's mostly done video games, but the Journey soundtrack is magical.

I would love to see Patrick Doyle or Brian Tyler, who did Thor and Thor: The Dark World respectively. I felt like their scores did a great job of making you feel both the power and the beauty of the fantasy environment they were working within. I’d also be totally onboard with the Bear McCreary suggestion, it feels like every time there’s something that makes me really emotional it turns out to have been him.

A slightly off-the-beaten-path composer that I personally think could do a really good job is John Paesano.

He scored the Maze Runner films, as well as Netflix's Daredevil series.  He's able to do the sweeping and epic types of pieces, as well as ethereal and otherworldly, both of which are things that Narnia's soundtrack will need. 

Here's one of my favourite pieces by him.
