He drinks and he knows things. He also wins Emmys.
In his accpetance speech, the actor thanked showrunners D.B. Weiss and David Benioff, GoT creator George R.R. Martin, and his wife, Erica.
"Thank you Dave and Dan for changing my life. I cannot walk down the street anymore," he said. "But you are honestly, the most talented, amazing people besides my wife."
This is Dinklage's third win in the same category for the same role, having taken home the same prize in 2011 and 2015 respectively. His fellow co-star Nikolaj Coster-Waldau, who plays Tyrion's older brother Jamie Lannister, was also nominated. Dinklage also beat out two other genre contenders, David Harbour (Stranger Things) and Joseph Fiennes (The Handmaid's Tale).
Tyrion has become a fan favorite amongst Game of Thrones viewers, thanks to his blunt attitude and bleak (and sometimes hopeful) outlook on life. He currently serves as Hand (aka top advisor) to Queen Daenerys Targaryen (played by Emilia Clarke).
