Before animating the song "Zero To Hero," the production crew went all-out and cast, choreographed, and filmed a shot-for-shot live-action version of the full number. They made costumes, hired a famed R&B choreographer, took over a warehouse, and used cranes to get fancy angles and everything. Co-director Ron Clements called it "the most elaborate video shoot we've ever done and I think has ever been done for animation."

Then they put the result of all their hard work in a drawer, where no one saw it for 19 years. At least they've already got this part down for when they run out of other Disney movies to remake with living human beings.

Ironically, in a movie with a chronology so jacked up that it requires an actual chart to keep track of, the most difficult part to shoot was in fact this tiny moment:
