The supervising animator responsible for bringing the Genie to life in Aladdin was Eric Goldberg. He was entrusted with an incredibly important task of animating the Genie to one of Robin Williams stand-up routines in order to convince him to accept the part. Goldberg reflected that Williams performance was always key to how he brought the character to life, commenting he wanted to make him "as broad-ranging as his vocal cords". In the new short film Once Upon a Studio, which celebrates the 100-year anniversary of Walt Disney Animation Studios, Goldberg not only handled Genie but served as the overall head of hand-drawn animation. The filmmakers used outtakes from the original Aladdin recording instead of AI to incorporate Williams voice into the short.
