One World, One Sky: Big Bird's Adventure

One World, One Sky: Big Bird's Adventure is a planetarium show in development for the United States and China. Designed as an introduction to astronomy for children, Big Bird, Elmo and Hu Hu Zhu will embark on a journey through space to learn about the sun, stars and constellations. On an imaginary trip to the Moon, the trio will discover how different it is from Earth.

In addition to teaching about outer space, the project's goals also include a stress on cross-cultural appreciation: the U.S. version will include an English and Spanish soundtrack with Hu Hu Zhu visiting Elmo in the United States, while the Chinese version is in Mandarin with Elmo visiting Hu Hu Zhu in China.

The film will premiere at the Beijing Planetarium on September 26, 2008, with the U.S. version set for release on October 15, 2008 at the Adler Planetarium in Chicago, Illinois.
