Sergeant Keroro the Super Movie: Take Back the Starry Sky! The Great Chase in the Solar System!! (超投影版 ケロロ軍曹 星空をとりもどせ！ 太陽系大追跡であります！！ Chō Gekijō-ban Keroro Gunsō Hoshizora o Torimodose! Taiyōkei Daitsuiseki de arimasu!!) is an animated film based on the Sergeant Keroro (known in the United States as Sgt. Frog) anime series. It was produced by Sunrise, the animation studio who also produced the anime series.
The film was supposed to be released in Japanese theaters in 2011, however, the release was eventually cancelled for unknown reasons. On August 2, 2014, Sunrise announced that the film would have a special screening at the Skip City Sai no Kuni Visual Plaza in Japan on August 2, 3, 9, 10, 17, and 24 of that year.
However, as of 2016, the film has yet to have a home media release or a TV broadcast in Japan. As a result, it is very rare nowadays and no footage of it can be found anywhere online.
