The best thing Nintendo could do is not copy any game when it comes to story. Make original stories for their films. Any attempt at recreating a game like OoT in a 2 hour film will never work. Zelda shouldn't even be restricted to 2 hours. If they ever make live action zelda films then it should be like LOTR and be a massive story told over 3 films.
Yea use familiar elements but let it be its own thing. Honestly, do what Square did with Final Fantasy: The Spirits Within but ya know... make it good
Spirits Within really stretched the take that all something needs are chocobos and a Cid to be a Final Fantasy.
The post-credit scene of this movie is going to reveal a shared Nintendo Cinematic Universe right? Doing a bunch of movies on Nintendo properties and having it culminate in a Super Smash Bros movie in like 2030 seems like something they'd do.
We we really need is a Luigi's Mansion film with Reese's as marketing so we get Boo-themed Halloween Reese's
