Prince Caspian - Will Turner wannabe?

I saw this photo of Prince Caspian and Edmund from The Chronicles of Narnia: Voyage of the Dawn Treader and I noticed the really close costume resemblance between King Caspian and Will Turner in At World's End. Maroon pirate-style shirt, scruffy, and hair style. I couldn't find a super great photo with which to compare, but if you've seen the movies, I think you'll definitely make the connection.
