Hey, sounds good! Johnny K. is right, but if you ever got the chance it would be good to know what fans want. The biggest problem I envision is Nintendo allowing it.

The real secret is to keep the Zelda feeling. Big, majestic landscape, quirky characters (not as quirky as Tingle, though,) monsters, magic, the usual. Assuming Link is in it, you have to be careful. Seeing a guy in a skirt is a bit... creepy. Make it a bit lower and straighter or something, like what you might see in Lord of the Rings but green. I can't say I know anything about movie making though, so this may not be worth anything.
