Don’t freak out. It’s none of the major players, like Tyrion, Daenerys, Jon, Arya, etc. Head behind the cut to see who’s likely been recast, who the new actor is, and which Game of Thrones character that actor has previously played.
Au revoir Callum Wharry, a.k.a. Prince Tommen Baratheon. If WinterIsComing.net is correct you’re being replaced by Dean-Charles Chapman, whom you may recognize as Richard Grey from the history drama The White Queen. Wharry’s Tommen has been absent for a while—he hasn’t put in an appearance since the penultimate episode of season two—and when he comes back in season four it makes sense that they’d replace him with a more experienced actor, seeing as Tommen will actually have, y’know, things to do.
Interestingly, Chapman’s filmography also includes season three of Game of Thrones, where he played Martyn Lannister, one of the squires captured by Edmure Tully’s army and later executed by Rickard Karstark against Robb Stark’s will. Granted, Martyn, at 15, is a good few years older than Tommen, but hey, that’s what acting is for. Hopefully Chapman’s new character will have better luck, though given we are talking about Westeros it doesn’t seem likely.
This news has gotten the fancasting corner of my brain whirring with ideas of which Game of Thrones characters it’d be fun to see played by other Game of Thrones actors. First off: Peter Dinklage should play everyone. Clone him in real life, pull an Orphan Black-style split screen, I don’t care. Lena Headey (Cersei) and Nikolaj Coster-Waldau (Jaime) could switch roles, just for kicks. Oh, and Maisie Williams (Arya) could be Tywin Lannister, striding around being all gruff and intimidating people. Nothing can compare.
