The late, great Robin Williams' Genie from Disney's Aladdin returns for the Walt Disney Animation Studios' new short film, Once Upon a Studio. The magical studio created Once Upon a Studio to celebrate its 100th anniversary with shorts that pull from Disney's long history and iconic content. Per The Direct, the short sees 543 animated Disney characters brought to life in a whole new world, and these characters would crossover and interact with each other — which, according to producers Brad Simonsen and Yvett Merino, presented its own challenges. Merino expressed that getting hand-drawn characters, like Flounder from The Little Mermaid, and CGI characters like Moana to interact was a hurdle they had to cross to "make them blend seamlessly" as though the two characters were walking and chatting with each other down the studios' hallway.
