robots in disguise

so, this comes via bree and is super cool.

she points out that it is vancouver in the background, which once she said it i realised, although i wouldn't have noticed otherwise. but my question is, why is the background for a UK citroen commercial vancouver?

if you're interested in how it's made you can find out here, thanks to marja-leena rathje who left this as a comment on bree's site.
