It’s been a while since we’ve heard anything on Greek mythology movie front, but two big-time casting announcements have been made with Liam Neeson and Ralph Fiennes joining the cast of Louis Leterrier‘s upcoming take on Clash of the Titans. Fiennes is still in the negotiation stages of the deal.

In the movie, the pair of actors will be taking on the top two gods of Greek mythology — one on the good side, and one on the evil. Liam Neeson will be taking on the role of the God of Thunder, Zeus; while Ralph Fiennes will use his skills as a creepy-ass baddie to embrace the God of the Underworld, Hades. The two larger-than-life beings are also siblings, with Hades on a destructive course toward trying to over-take his brother and rule all of Mt. Olympus.

Also starring in the movie is Sam Worthington (Terminator Salvation, Avatar) as son of Zeus, Perseus; Mads Mikkelsen (Casino Royale, King Arthur) as Draco; Gemma Arterton (Prince of Persia, Quantum of Solace) as Io; and Alexa Davalos (Defiance, The Mist) as Andromeda.

Clash of the Titans is set to begin filming this month with a release March 26, 2010. Leterrier is best known as the director of Transporter 2 and The Incredible Hulk. The script is penned by Lawrence Kasdan, who also wrote Star Wars Episode V: The Empire Strikes Back, Star Wars Episode VI: Return of the Jedi, and Raiders of the Lost Ark, among others.
