The official website for the anime project adapting Key's planetarian ~the reverie of a little planet~ visual novel unveiled a new trailer and key visual for the upcoming anime film planetarian: Hoshi no Hito (planetarian: Star Person) on Thursday. The video previews Lia's theme song "Hoshi no Fune" (Starship).

Daisuke Ono and Keiko Suzuka are returning to play Kazuya and Yumemi Hoshino, respectively. Additional cast members include (official name romanizations not yet revealed):

Tamio Ohki as "Hoshi no Hito" (Star Person)



Sanae Fuku as Revi



Yōko Hikasa as Yobu



Minami Tsuda as Rutsu



The film opens on September 3.

The planetarian anime project includes a five-episode anime titled planetarian: Chiisana Hoshi no Yume (planetarian: The Dream of the Small Star) in addition to the film. The net anime, which premiered on July 7, adapted the main game's story, while the film will be "another story" about what happens to Kuzuya afterward.

Funimation streamed the net anime and will premiere the English dub on Thursday.

Naokatsu Tsuda (JoJo's Bizarre Adventure series, Inu X Boku Secret Service) is directing and writing both projects at David Production (JoJo's Bizarre Adventure series). Shogo Yasukawa (Terraformars, Food Wars! Shokugeki no Soma, JoJo's Bizarre Adventure) is writing the scripts alongside Tsuda. Katsuichi Nakayama (Nishi no Yoki Majo - Astraea Testament ) and Shunsuke Machitani (episode director for Oreimo, Kurokami The Animation, JoJo's Bizarre Adventure: Stardust Crusaders) are the series directors. Hitomi Takechi (Hyperdimension Neptunia) is adapting Eeji Komatsu's original character designs for animation.

Visual Art's/Key (Clannad, Rewrite, Angel Beats!) originally released the planetarian ~the reverie of a little planet~ "kinetic novel" in Japan on personal computers in 2004 before porting it to the PlayStation 2 and PlayStation Portable consoles. The story takes place 30 years after a world war put a halt to space development. The protagonist, simply known as "the Junk Hunter," attempts to restore a planetarium's projector after meeting a robot.

Sekai Project licensed the PC version of the game and released it on Steam. VisualArt's also released an English version for iOS.
