I'm afraid i don't agree with you on the 'next to no words' type of Link.
Link is the main character, the main character needs to appeal to the audience,
and this will be achieved on how he is portrayed through out the films.

My intention was to start Link as a cheeky, sarcastic and yet with a heart of gold.
Through the events of the films, he would mature, and become serious with in what has happened.

The mythology of zelda's backround is never perminant from game to game, thus there is no need to stick to her being a sage.

Remember, this would be set before any of the games, and has no relation to them. This allows for the story to be flexible, and surprising.
