"We wrote an opera. So, who would've thunk it?" Zimmer said. "It just came out of a conversation with Marc that came out of all these ideas and suddenly, you know, there was this great moment where (Pharrell) was so excited because of all these ideas. I could see all of these ideas sort of flying in his head and he said, 'Stop. I just have to walk around the block, literally.' We sat there and he walked around the block and came back with two pages of lyrics. Amazing. It was amazing but it was that sort of environment."
