Why

Go to the States to make this load of poo?
Pay cheap 2bob actors and fly them out to the USA. I mean they could have found better actors than Nicola Bertram she was DIRE, stick to Eastenders
She was more wooden than a piece of wood!
Im sure they could have used cheap American actors with fake accents and saved a packet.

Or

Gone down the East End, and used a few old rundown buildings, than at least they would have got the weather right

The Director and Company must have money to burn
