*Game of Throne* edited out lot of character/stories from books like Lady Stoneheart (which is [discussed here](https://movies.stackexchange.com/questions/74865/is-lady-stonehearts-absence-from-the-show-explained)) and even shorten story of few characters like Cold Hands (which is further [discussed here](https://movies.stackexchange.com/questions/21383/why-was-the-character-coldhands-not-introduced-in-season-4-when-he-was-in-the-b)). And same happen to many Dorne characters and story arcs.


But one character who had a significant story in Dorne arc in book did appeared but never called by that name and didn't even show his face

[Arys Oakheart](http://gameofthrones.wikia.com/wiki/Arys_Oakheart)

His work is to protect Myrcella Baratheon in Dorne but even after 

>! the death of Myrcella Baratheon

he didn't even shown his face. What was the reason for not showing his face? Did they even cast anyone for that role or it was always played by some random extra?
