FX's buzzworthy upcoming drama 'Tyrant' has made a few strong pushes in its casting thus far, but has finally elected its leader. UK actor Adam Rayner nabbed the main lead, the head of a family that finds itself embroiled in Middle Eastern politics, though Rayner's casting will likely take precedence over the actor's starring role in the proposed 'Saint' reboot.

Via Deadline, we've learned that Rayner will take the role of Barry, head to the unassuming family that ends up caught in a world of political intrigue. 'Weeds' star Justin Kirk will play mysterious American diplomat John Tucker, while former 'Mob Doctor' Jordana Spiro will take the role of Dana, wife to Kirk’s Tucker, with whom she works at the American Embassy as a cultural attaché.

Developed by ‘Homeland’ producers Howard Gordon and Gideon Raff, along with ‘LOST’ writer Craig Wright, ‘Tyrant’ centers on a family (Barry, Molly and children) that gets drawn into Middle Eastern politics when an Arab state dictator dies and leaves his American son as the new head of the country. ‘Life of Pi‘ director Ang Lee had originally signed on to helm the pilot episode but was later replaced by ‘Harry Potter‘ franchise vet David Yates.

For his part, Rayner filmed the title role in a proposed reboot of 'The Saint' with Eliza Dushku and Roger Moore, though the project seems to have failed in taking off. Tell us in the comments if you're interested to see what FX comes up with for 'Tyrant' in shooting later this year!
