In choosing the locations, really the only thing that I was focusing on was, 'What would be appropriate for the time period?'

There are places in the script where we use specific Americanisms, we use specific anachronisms as well, and that's quiet purposeful. The Americanisms are there on purpose, the anachronisms are there on purpose. If Shakespeare can have a clock in Julius Caesar, we can have people say, 'Stick up your bum,' in 1830s England, so those things are purposeful.

For the places, I wanted to make sure that we were choosing ones that would be visually interesting when they animated it, but also that would be accurate for the time period - that would stand out. The church at St Mary Le Strand is such an amazing location [as is] the Strand in general from that period.
