Its all filmed here in Northern Ireland and loads of my friends have been extras. Another girl I know played one of Vare's "little birds" in the last series too.
The harbour of the Iron Islands was filmed about a mile from my house and I recognise loads of the locations as we have some amazing scenery around where I live and they used loads of that.
When filming the last series they had a big tent village setup along the coast. The wind blew the lot down and injured a load of people.
HBO have brought loads of money into our local economy. Seams everyone I know is working as an extra or building sets. They also donate money to the local communities when they shut down their harbour to film or whatever. They are using the Massive Harland and Wolff buildings in Belfast (where they built the titanic) to do all the indoor stuff.
Good times for the film industry here. Looking like the next promethious film is going to be filmed here too.
