Game of Thrones is celebrating its 10th birthday today but 11 years ago, when season one was shot in Malta, no one could have imagined it would grow into a global TV phenomenon. The HBO mega-series soon had fans travelling across the world to visit filming locations. At its humble beginnings, the source material was a popular novel series with a huge cult following. But beyond that, there was none of the hype later associated with the brand, the Malta Film Commission (MFC) said. Most of the actors, with the exception of Sean Bean, were still relatively unknown. The same cannot be said of Jason Momoa, Emilia Clark and Maisie Williams today.
