Internet Shocked to Learn Game of Thrones Actor Played 2 Parts Those Lannisters all look the same By Michael Harthorne, Newser Staff Posted Jun 11, 2016 12:46 PM CDT 8 comments Comments Peter Dinklage, who lazily plays only one role on "Game of Thrones." (Helen Sloan/HBO via AP) (Newser) – The internet loves obsessing over Game of Thrones, so Hello Giggles wants to know why more people aren't talking about the fact that "Tommen is also his own cousin." Dean-Charles Chapman currently plays King Tommen Baratheon on the show, a role he took over from a younger actor in 2014. But he also played Tommen's cousin, Martyn Lannister, in a few episodes of the show back in the third season, Mashable explains. Hello Giggles thinks the recasting makes complete sense. “Given the Lannister family’s penchant for incest, having several people in that lineage look the same (like exactly the same) would not be a surprise.” Poor Martyn was killed off after being taken hostage by Robb Stark, and Bustle thinks Chapman better hope for a third role as Tommen is "probably doomed just like his look-alike cousin."
