Festival of the Lion King at Disney’s Animal Kingdom opened with the park in April 1998. The original theater in Camp Minnie Mickey was not fully enclosed. The show ran in this theater until 2014 then moved to a specifically built theater in Harambe to make way for Pandora the World of Avatar. Here is video from my first viewing of the show in December 1998.
For comparison here is a clip from 2016 and the new theater.
Hong Kong Disneyland also features a show called Festival of the Lion King. Here are some video clips from that show:
