It is the fault of London Underground for refusing basically to negotiate properly.

London underground took me on a tour of all the hidden places, the disused shafts and staircases... that was very interesting.

I had originally done a production called 'The Resistance.' It was one of those underground guerilla things, very low budget. Then Starz and Ghost House ended up picking it up and funding it, and we reshot it.

You negotiate every day with friends, family, customers, and business associates.

The Iranians are tough to negotiate with,

I didn't know they could hive underground like that.
