Pre-production for Sofia the First goes on in the Yahoo building near the Burbank Airport. Work on the series has been going on for much of the year. (It's a CG show and demands on the artists are high.)
There's lot of musical numbers and lots of production. Also lots of demands for quality placed on the artists. Disney's had a goodly amount of production money riding on the project, so it must be a relief to the crew members to know that the maiden effort has paid off.
With luck and the right time slot, the series will be a long-term winner.
