I don't want an adaptation from a single game. I will accept it if done right, but it is more likely to fail because the writer stuck to the game structure too much or even so little that the movie didn't seem like Zelda at all. The game
OoT would be the one that would probably work best for a movie. It has a story line with twists that can be adapted, and it has several people who Link get's to know. These characters add depth to the game and would significantly increase the appeal of the movie.
OoT has enough detail as a game to be adapted into a movie, but it also has the ability to be molded into a more believable form as a movie. Taking the dongeons and doing them all walking through the rooms is not an option, and I think we all know that (I hope) I will give my basic template for the forest temple.
Link meets Saria outside the temple, (Dialogue) they both enter together and they're walking along catching up over time lost. Link hears whispering from different areas, but Saria can't hear a thing. He ignores it until one of the Poe sisters appears in front of him. Now Saria is caught off guard but Link has been alert for something like this. She tries to distract Link while the others sneak up from behind. Saria is knocked unconcious and he is left to fend for himself. He defeats them with the master sword and magic.
Shortly afterward, Link enters a room later on after a flashback to his time as a Kokiri. Link is forced to carry Saria and when he enters this room he sees Ganondorf. (we know it's Phantom Ganon, but they don't) Dialogue. They fight but Link needs Saria's bow. While she's unconcious she speaks to him. giving him knowledge to use the bow. He kills the horse first and it's fun to watch. Phantom Ganon is wounded by the master sword. the real Ganon appears and admonishes the phantom for failing him. the real Ganon kills the phantom. Ganon then mocks Link and gives him an offer to become his right hand man. Link obviously denies.
This is a way to keep basic elements of the game, but also give them the story of a movie. keeping them realistic.
