When the movie was first announced in November 2015, the project was in its very beginning stages and the script at the time had just recently been greenlit.  Prior to that announcement, Craig and the other writers spent three days breaking the story.  The movie later entered full-on production on March 2016, after the announcement made at Nick's TV Upfront. The main voice recording sessions and a table read with the cast were done around April/May, and storyboarding was done during the summer. By October, the movie was in the animatic stage, and the last rounds of voice recording were done in November. In January 2017, the movie's finalized materials and storyboards were sent to Saerom in Korea for final animation. The film began post-production a few months later, when finalized animation began to come back. The movie was locked and began being scored by October 2017. It wrapped up production in early November, about two weeks before its premiere.
I decided to put past considerations aside for the moment and try to look at the bigger picture. The Chaconne was divided into three large sections. The dark and brooding outer sections flanked a hymnlike inner one that evoked peace, gratitude, and optimism. Was it far-fetched to think that Bach, a devout Christian, might have offered the Chaconne as an expression of the Holy Trinity, its bedrock spiritual principle? The first section, in D minor, would represent the Father; the next, in D major, the Son; and the final section, in D minor, the Holy Spirit. This line of thought intrigued me, even though I was on shaky footing as a secular Jew with only the flimsiest knowledge of Christianity. The more I looked, however, the more "threes" I found. The Chaconne's basic building block was a three-beat bar, the initial theme appeared three times — at the beginning, the middle, and the end — and then there were those evocative three-note groups that appeared over and over again. Was the Chaconne some kind of message in a bottle destined for (dare I think it?) God?
During the prejudging we sat at the back of the hall, there was a bar near us serving beer. I said to Arnold "Why don't we have a few beers to loosen up", there were many people asking for autographs as well. We must have had at least 4 beers, the guys name that was running the show was Frank Burwash, Arnold asked me what the name of the guy running the show was, I said as a joke "I think it is Frank Bird Bath or Frank Bird Watch" Arnold said "That is a strange name". When Arnold got on stage to talk he said "I would like to thank Frank Birdbath" and Frank yelled out "BURWASH" and then Arnold corrected himself "I mean Bird Watch".
