The Legend of Zelda: Skyward Sword
For the uninitiated, Skyward Sword may feel a left-field pick. In actuality, it is the beginning of the canonical Zelda timeline, the place that sets up the tropes of the hero, the princess and the ancient evil to be reborn time and time again. It does also include Groose, who has a fantastic quiff. This feels like a relevant place to start, however, while Demise is exceptionally evil in his own right, it feels inevitable that the first villain in a Zelda movie would be Ganon or Ganondorf. Skyloft, while an excellent locale, also isn’t exactly what people would recognise as Zelda’s traditional Hyrule.
The Legend of Zelda: Ocarina of Time
Ocarina of Time was Zelda’s first foray into 3D and could again prove to be the ground-breaking step for the franchise. It’s a relatively standard story for the Legend of Zelda, and the opportunity for ocarina solos is tantalizing. It also would act as a good introduction to the aspect of sages in the series. It hits off many of the classic locales in Zelda, including the Great Deku Tree and Gerudo Desert. Given the time travel that occurs, it also gives an opportunity to see two unique portrayals of Link, and opens up the rest of the timeline for films. Whether they choose to go with the Adult, Child or Downfall timeline, I'll leave up to them.
A prequel to The Legend of Zelda: Breath of the Wild
Ok, admittedly this one is technically cheating. But thanks to Hyrule Warriors: Age of Calamity, quite a lot of the groundwork in this idea is already in place. The premise is simple, how Hyrule lost to the might of Calamity Ganon, rather than the alternative timeline offered by Age of Calamity. This would be the ideal way to open up a trilogy of films, a gritty war that ends in tragedy for the heroes. Following this, the events of Breath of the Wild, and Link's revenge tour against Calamity Ganon. And finally, taking place in the time of Tears of the Kingdom, for the final Hero’s duel between Link and Ganondorf. The final boss is intense enough in-game, the intensity of the sword fight in the depths of Hyrule would be a true sight to behold on the big screen. Though I would be both excited and terrified to see the Goron's in a live action film...
