Hello everyone.

I am pleased to announce that this afternoon I attended the first session of the The Chronicles of Narnia: The Voyage of The Dawn Treader,
AND YES Nat appears in the movie!!!.

Appears in a cameo, as shown Tilda Swinton. Nat appears towards the end of the film, appears as a mist that transformed the face of the Caspian's father, and tells to Caspian that he is ashamed of him. But this is just a nightmare, or a sort of appearance by an evil spirit, to demoralize and humiliate to the King Caspian.
Nat comes only a few seconds, but I'm sure that is our Nat, because I've been to see the credits in the end. I feel very happy to see Nat. I've been very careful

all the time to see to where appeared, and finally I have seen him

.
Today I really enjoyed this movie, because in addition to see Nat, the movie have a lot of action, and I have seen in 3D, and you know that happened to me? like was the first session, I was alone in the whole Cinema hall, the rest of the people were in the other room was not 3D and the price was cheaper. So I have been privileged that I have screened the film for myself

.
See Nat has made me feel a little better, after the tough times I'm going. Always is so nice to see Nat at the cinema screen!!.
Well, now we have the answer:
YES, Nat appears in Chronicles of Narnia, in the performance of Caspian's father.
