Mark Strong is known for playing various villains in movies (Kick-Ass, Green Lantern and Sherlock Homes) and it seems he might continue this typecasted villain role in Total War: Rome 2. He is set to play General Silanus, a power hungry general that will guide you (the player) though the opening chapters of the campaign.
Even though he is mostly known for his villain roles, he did play the voice of Titus in the Warhammer 40k: Space Marine video game. Which is a pretty damn good game and is now published by SEGA (since it was developed by Relic).
