The First IMAX Film Released at Expo '70 in Osaka, Japan

1970, the first-ever IMAX theater was opened at Expo '70 as the Fuji Group Pavilion. The film screened was the 17 minute short documentary "Tiger Child".
It was an innovation from the multi-screen system with five synchronized screens arranged in a cross shape, demonstrated at Expo 67's Labyrinth Pavilion, and the birth of the most extraordinary motion picture format in history.
According to the brochure at the time, the screens measured 19 meters by 13 meters, and the projectors were produced and maintained by Canon, a keiretsu of Fuji Bank, which invested in this project.

The year following the record-breaking Expo that drew 64 million visitors, this IMAX projector was transferred to Ontario Place's Cinesphere in Canada, the world's first permanent IMAX theater, where it ran for 40 years until it was replaced by a 3D model in 2011.
2015, Japan's first IMAX with Laser opened at Expocity, the former Expo ‘70 site. This place still remains special for IMAX.
The original negative film of Tiger Child is securely stored at the IMAX headquarters in Los Angeles, alongside works by James Cameron and Christopher Nolan.
