Game Of Thrones: 18 Actors Who Were Replaced

10. Joss Stilwood (The Mountain's Squire)

The Replacement: James McKenzie Robinson

Barely anyone in Game Of Thrones is deemed not important enough to get any attention: even the most subtly involved characters seem to get a full backstory and links to other famous family members. But that isn't the case for Joss Stilwood, squire to The Mountain who has appeared at least twice.

He was initially played by veteran bit-part actor Niall Cusack in A Golden Crown and reappeared in the fourth season to squire for The Mountain once more played by Hollyoaks actor James McKenzie Robinson. Chances are, you barely noticed that he existed, let alone that he was replaced.
