It deals with walt disney animation studios in the 80's up until the lion king. It was very eye opening into just how much trouble wdas was in pre the little mermaid.
This might not be from that documentary but i remember the producers of the lion king calling each other to tell them that the lion king was a major success the morning after opening day. 44 million i think? Not huge numbers by todays standards but todays ticket prices are higher. The movies success was not guaranteed, it was a major risk throughout the development process.
Nobody at wdas predicted that the lion king would become the highest grossing movie worldwide at nearly 800 million, which was an incredibly large amount higher than any other disney film released in the past.
