Sony Pictures uploaded a 10-minute preview of the film, but it’s not the new 4K version. Probably to tug at the nostalgia of those who watched the original way back when, to get them to buy the new 4K version. Which is a weird slice of the movie to show, since it’s the slowest part of the Advent Children movie.
For those who are fans of the original game and the movie, this may be something you’d want to watch. Even if it’s only to see what the film would look like when given the remaster treatment. But if your first Final Fantasy VII experience is the remake, then it’s probably not a good idea to watch this.
