15 WORST Performances In Game Of Thrones
8. Dean Charles Chapman - Tommen Baratheon (Seasons Four And Five)
Similarly to the previous entry, this only applies to some of the character's run.
Tommen Baratheon was an OK character, but Dean Charles Chapman didn't do particularly good work as him in seasons four and five and was fairly wooden.
This is understandable. Being a young actor is very hard and most of them struggle to give entirely convincing performances at a younger age. Still, this was one of the show's worst performances back then.
Still, like many other young actors, he's improved with age. He was fine in season six and also did a good job in the recent film 1917 as one of the leads, so Chapman undoubtedly has a good future ahead.
