Ralph Fiennes in talks to play Hades in Louis Leterrier’s “Clash of the Titans”. Ralph Fiennes is in talks to star as Hades, the lord of the underworld, in helmer Louis Leterrier’s “Clash of the Titans”. “The Reader” star would join a cast that already includes, Gemma Arterton, Sam Worthington and Liam Neeson in the reimagining of the Greek myth of Perseus. Fiennes is also in talks to star in 1970s-set coming-of-age comedy “The Men at the Pru,” which Ricky Gervais is co-writing and directing with Stephen Merchant. Whether he joins the projects is now down to scheduling. The actor is looking to complete as many works before returning to his role as Voldemort in the final Harry Potter installment, “Harry Potter and the Deathly Hallows: Part II,” which begins production in the autumn.
