This is more of a basic rundown than anything.
Kazama Shunsuke will be reprising his role as Yugi Muto for the Japanese version of the film.
It will be a full length feature movie. (So at least closer to hour and a half at least, none of this 50 minute short flick that Bonds Beyond Time did)
Kaiba and Yugi get minor redesigns/tweaks to align with the franchise’s more recent art style.
The movie is an original story set after the original series/manga.
