Our Uriah, as confirmed very recently today is Australian Actor Keiynan Lonsdale. If he looks familiar, you may recognize this guy from the popular Australian show Dance Academy. He was not in the first season, but he made some appearances in the second season and became a main character in the third and final season.
I was just minding my own business writing my Top Ten Tuesday, when my friend texts me the picture of Keiynan officially confirmed for Uriah and I was screaming. She watches the show as well so you can tell we were both really excited. The entire DA fandom was excited as well as the Divergent fandom.
If you don't know who Uriah is, he was mentioned in the first book, Divergent as a Dauntless-born Initiate who befriends Tris throughout the book. He is also close with other Dauntless-born initiates like Lynn and Marlene, who were also recently cast as well. Rosa Salazar as Lynn and Suki Waterhouse as our Marlene.
Uriah is described like this in Divergent:
tall, bronze/brown skin, dark eyes, handsome, snake tattoo behind his ear (tail curls around his earlobe), tattoo at his waist (Ch. 21, p. 272)
