With a cast as massive as that of 'Game of Thrones', sometimes recasting certain roles is just practical. The series has already replaced actors in the roles of Ser Gregor "The Mountain" Clegane and Beric Dondarrion -- both initially background characters with more significant roles going forward. And now, it appears, the show is doing the same for a Lannister.
The role of Tommen Lannister -- Joffrey's little brother -- will be played by Dean-Charles Chapman in season 4. The round-faced princeling was played by Callum Wharry in the first two seasons of the show, but did not appear at all in season 3.
As fans of the book series know, Tommen becomes much more prominent at this point in the story -- he even gets speaking lines! -- and it's important to have a capable actor in the role.
If you're wondering where you've seen Chapman before, though, that's because he's already been on 'Game of Thrones.' That's right -- the actor appeared in season 3 in a completely different role: that of Martyn Lannister, the young prisoner killed by Robb Stark's bannermen. Of course that was a bit part, and it seems unlikely that he'll be remembered -- or recognizable -- in his new role.
This news was originally broken by WinterIsComing.net, and HBO has not (as of this writing) made any official confirmation of Chapman's casting.
What do you think of the newest member of the Lannister family?
'Game of Thrones' season 4 will premiere in spring 2014.
