Kid Icarus and Zelda would do pretty well if they got it right. Hopefully it happens!

Fire emblem series:
- They have HOT and SEXY male and female characters which they can put some "ecchi/fanservice" touch on it. Which both guys and girls can nosebleed over.

- If they can, i want Ufotable to make it for them. If you've seen Fate/Zero or Fate/Stay Night Unlimited Blade Works, then you would know how awesome their art style is. Especially those glorious action scenes!!!!! Plus those 2 animes has that "historical" theme which FE kinda have......

I could easily see a Metroid movie working as a Sci-Fi thriller where Samus along with some federation soldiers have to come to an unknown planet to investigate a disturbance or help rescue some federation forces that they lost contact with.  The movie wouldn't even have to necessarily have to be carried by Samus entirely; it could be a scenario where the entire investigative team is wiped out save for one character and Samus with the majority of the movie spent with them trying to get the hell out of there. Samus could spend the movie being a larger than life, poker-faced conundrum going through these events as if it's just another day for her while the other character could work as the one that's more relatable to audiences and grounds the film emotionally.  This way, Nintendo doesn't have to commit to any back-story or character development with Samus and you get a viable Metroid movie.

I'm still against Link speaking so I would say no, unless he doesn't say anything, but then that anime would be pretty bad..

Fire Emblem or Kid Icarus would be my pick
