It hasn't happened yet, but they are showing interest in it.
Paramount has acquired the rights if I recall in news several days ago..
Makes you wonder how the outcome will be, I believe 100% the miko and sake scene will be replaced with some original story, that and the age difference will somehow changed.
I think Kimi no Na Wa can be translated kinda fine though. The issue I see with other adaptations lies more in trying to compress 20+ episodes of animes into a 2 hour movie, which kinda forces them to try and bullshit up a new story altogether(Death Note, DBE) or made the plot and themes extremely paper thin(Ghost in Shell, Jojo).
If it was 2 hours movie > 2 hours movie. I think eh, it might be workable. Still very pointless, but I guess you can still make something competent.
Dragon Ball Evolution failed so hard as an adaptation of Dragon Ball. The same thing might happen to Kimi no Na Wa and I imagine Goku saying “It’s your turn”
