5. Jason Isaacs
The former Lucius Malfoy has already played Ra's in the superb DC animated movie Batman: Under the Red Hood. He nailed the intellect and aristocratic bearing of the character, essential for the man who views himself as royalty and the future leader of the world. He also has the height to be a good physical match for Stephen Amell. Isaacs is no stranger to American television, having a memorable guest arc in the West Wing, and starred in the shows Brotherhood and Awake. If he joined Arrow he'd be adding to the shows already sizeable British contingent, his Resident Evil co-star Colin Salmon, Alex Kingston, and Paul Blackthorne (who would be a strong candidate himself if he wasn't already on the show).
