Hey, Carlton...Love the podcasts and hope you'll answer a question for me this week!

We've heard that LOST is shot "entirely" in Hawaii...which means your location scouts must find places on the islands to recreate Nigeria and other exotic locales...But in "Fire + Water" we see Charlie chasing after the director of the diaper commercial, and there in the background is the Battersea Power Station (and that pesky easter egg sign)! My question is...Was that scene actually shot in London...or was the B.P.S. building inserted later in post production via CGI? It sure looked like the building was really there to me!

Thanks, and keep up the great work!

EDIT: Having seen "One of Them", I can say the Iraq exteriors in Sayid's flashback looked very CGI, especially the end shots on the road...But Charlie's flashback didn't even remotely look like a CGI shot. So, my question still stands!!
