Just a couple of weeks ago, a group of Zelda fans released a Zelda fan film, entitled The Hero of Time. Unfortunately, it looks like Nintendo decided that all this free publicity for their series was a bad thing, and ordered the film removed from the internet.
A fan film is basically no different from fan fiction, or fan art - just a way of paying homage to the Zelda series through the medium of an internet video. What reason would Nintendo have to close it down? Will they next shut down other Zelda fan works such as Zelda Reorchestrated?
