Game Of Thrones: 18 Actors Who Were Replaced

16. Callum Wharry (Tommen Baratheon)

The Replacement: Dean-Charles Chapman

You really have to feel for the Baratheon/Lannister kids. Not only were they all killed off in wonderful ways, but two of them were replaced with pretenders just as their roles were getting good.

The first to be shunted out was Callum Wharry, who played Tommen Baratheon when he was little more than background furniture. When it came to him sitting on the throne in Joffrey's wake, it was clearly decided the youngster wasn't up to it and he was replaced with Dean-Charles Chapman, who masterfully captured Tommen's inherent annoyance as well as being a slightly less creepy marriage option for Margaery Tyrell.
