Jacob Anderson, born 18 June 1990 in London, England, UK, is an actor. He has appeared in the TV series Episodes, Silent Witness and Primeval, as well as the movie Adulthood.
All of Grey Worm's lines in Season 3 were in Low Valyrian. Linguist David J. Peterson, who designed all of the languages on the TV series, heaped massive amounts of praise on Anderson in his blog throughout Season 3. Peterson is in outright awe of Anderson's skill at delivering lines in his constructed languages: Anderson perfectly matched the stringent pronunciation rules which Peterson devised for his constructed languages - which was praiseworthy in and of itself - but in addition was able to emote and act the lines flawlessly. That is, Anderson didn't just learn the lines as a string of sounds, but paid close attention to what each verb and noun are so he knows which words he should logically be emphasizing - subtle nuances that only a fluent speaker of Low Valyrian would really be able to detect. Anderson's skill at Peterson's constructed languages rivals that of Emilia Clarke. Peterson would go on to lament every episode in which Grey Worm had few or no speaking lines, i.e. in "The Bear and the Maiden Fair (episode)", Daenerys orders Grey Worm to deliver her terms to Yunkai's leaders, and he acknowledges with a simple nod, but Peterson lamented that he didn't compose a paragraph-long and flowery speech for Grey Worm to give expounding upon why he was happy to follow the order.
