RE: (2) Another 15th Movie Trailer, Keldeo and Meloetta Downloads for 15th Movie [2/29]
A little last bit of info from the official movie site. In Yuyama's comment, he states that as oppose to last movie theme of "black" and "white" and "heroes", this movie is going to be focused on "friendship" and "nakama".
What kind of stage is "Kyurem vs Sacred Swordmen" set in?
Deep inside the moutain, there is an extremely cold, abandoned iron forge kind of place. The Sacred Swordmen Cobalion, Terrakion, Virizion meet Kyurem in such place. When the Sacred Swordmen challenge Kyurem into a battle, Kyurem created a battle field called the "Ice Dragon Gate" and told them "come to me through that gate". I (Yuyama) think that the battle field at the site of the abandoned iron forge is a hard (as in hardcore) and awesome thing.
More accurate translation of the movie's premise
Ash, Pikachu, Iris, and Cilan is heading to their next destination, Roshaan. Inside the train the run along the moutain side, Ash and friends discover a wounded pokemon that they have never seen before.
That is, the illusious (Maboroshi) pokemon, Keldeo. The 3 pokemons that protect the world and pokemons and are known as the "Sacred Swordmen", Keldeo is said to be their successor.
There, suddenly, the world strongest dragon pokemon, Kyurem, appears and attack Ash and friends. Changing its shape to Black and White Kyurem, it stands before Ash and friends with domineering power. Ash and friends narrowly escape Kyurem's pursuit.
The battle with Kyurem, who is pursuing Keldo, on the running train and while flying on the blimp! Can Keldeo, Ash, and Pikachu overcome this danger? The need to save friends, along with true power of bravery, and the friendship with Ash and friends, call forth the unknown power of Keldeo.
