'Beautiful World' is a music video directed by Tsurumaki Kazuya and sung by Utada Hikaru.

Tsurumaki served as an assistant director under Hideaki Anno in Gainax's landmark series Neon Genesis Evangelion, in which role he handled production, art director and setting assistant for some episodes. In 1997, he directed episode 25', the first half of the cinematic conclusion to the Evangelion series, The End of Evangelion. In 2000, Tsurumaki officially made his debut as a full-fledged director with the six-part OVA series, FLCL. In 2004 he directed the hit sequel to Gunbuster called Aim for the Top 2! or Diebuster.

Utada is best known by international audiences for writing and producing four theme-song contributions to Square Enix and Disney's collaborative video game series Kingdom Hearts: "Simple and Clean", "Sanctuary", "Don't Think Twice" and "Face My Fears". <3

The Song in question is based on the ending theme for Rebuild of Evangelion: 1.0 You Are (Not) Alone. As for the video itself, it uses clips from the first 3 movies of the rebuild franchise. It uses city scenery along side cuts to stills of the characters. The characters themselves are juxtaposed with those same buildings and finally quick cuts to scenes of the movie. These cuts involve most of the main cast members and their interaction around Shinj. Presumably used to link with the music's lyrics as to why said images were chosen.

Even as a fan of Utada Hikaru's music, thanks to Kingdom Hearts, the song itself is only half of the original itself. So if listening to the song was your only take away, then you are out of luck.
I will say for a positive that even if most of the images were just reused scenes, the placement of them was effective. In terms of the conjuncture with the songs themes and lyrics with the themes of the movie. Otherwise the main use of this was for promotion of not only the last films for fans, but to be showcased at an MTV Japan event to promote said movie and franchise.

Harmless is a word I would use. Neat for fans of Eva and Utada and a small piece to hold off people waiting for the last film, but absolutely little to nothing past the 1st or 2nd viewing for those unfamiliar with both.
