Winter is coming and, worryingly for Game of Thrones fans, Brexit may be too.

If Britain votes to leave the European Union in Thursday's referendum, it may be more difficult to film HBO's smash hit series.

That's because Northern Ireland provides the backdrop for many of the show's most dramatic scenes, including the Battle of the Bastards from last week's episode, and the EU helps subsidise the cost of production.

Should the UK leave the EU, those funds would potentially dry up.
