LOS ANGELES (Hollywood Reporter) - Mads Mikkelsen, Gemma Arterton and Alexa Davalos are joining the cast of “Clash of the Titans,” the Greek-god epic being directed by Louis Leterrier.

Sam Worthington stars as Perseus, who embarks on a quest to save a princess and defeat Hades, the god of hell. Matt Manfredi and Phil Hay wrote the script.

Mikkelsen is playing Draco, a skilled fighter and leader of the Praetorian Guard that accompanies Perseus.

Davalos is Andromeda, the captured princess, and Arterton plays Io, who is instrumental in bringing the winged horse Pegasus to Perseus.

The Warner Bros./Legendary Pictures project will begin lensing in the U.K. at the end of April.

Mikkelsen, one of Denmark’s most recognizable faces, is best known to American audiences for his role of the villain in “Casino Royale.”

Arterton, who appeared in the James Bond film “Quantum of Solace,” next appears in Richard Curtis’ “The Boat That Rocked” and opposite Jake Gyllenhaal in “Prince of Persia: The Sands of Time.”

Davalos most recently was seen in “Defiance.” Other credits include “The Mist,” “Feast of Love” and “The Chronicles of Riddick.”
