Alexa Davalos

Mads Mikkelsen (Casino Royale / King Arthur) and Alexa Davalos (Chronicles of Riddick / The Mist) have been cast in key roles in Clash of the Titans.

Mikkelsen will play Draco, a skilled fighter and leader of the Praetorian Guard who accompanies Perseus (Sam Worthington) on his epic mission.

Davalos will star as Andromeda, the captured princess whom Perseus sets out to rescue.

Additional cast include Gemma Arterton (Quantum of Solace), Liam Cunningham (First Knight / The Mummy: Tomb of the Dragon Emperor), Hans Matheson (Deathwatch / Sherlock Holmes) and Luke Treadaway (Dogging: A Love Story / Brothers of the Head).
