Once Upon a Time... Planet Earth (French: Il était une fois... notre Terre) is a French children's television educational animated series directed by Albert Barillé. It was produced by Procidis and France 3 with the support of the Centre National de la Cinematographie, the Directorate-General for Research of the European Commission and the European Broadcasting Union (EBU). The series was initially broadcast since 22 December 2008 on France 3. This series was the belated finale of the Once Upon a Time... educational television franchise, and its original premise was set up from "Once Upon a Time... the Earth (and Tomorrow?)", the final episode of the first series Once Upon a Time... Man, thus finally going back to the beginning where it all started and ended. The series' premiere also coincided with the 30th anniversary milestone of said educational animation franchise.
