I mean come on.. all the leads are like 25 years old or something and look like boys not MEN! is this show taken place when the characters were in their teens? or something? no wonder the show got axed, it's pure BS!
Not really. The only one who looks like they could be in their teens is the actor playing Arthur, and perhaps Guinevere. Are you telling me Eva Green and Joseph Fiennes look like teenagers?
I'm with maksavorst, I don't get the "ALL the characters" part of your comment, OP. As far as Arthur and Guinevere are concerned: yes, the story takes place at the beginning of the Arthurian timeline, so it' slittle wonder they look young. The only precise age that I know of in a medieval Arthurian text is 15 when Arthur draws the sword from the stone, so if they had gone with it they could even have cast much younger leads.
Tamsin doesn't look like a teenager to me....She actually seems like she could be older than Arthur. Maybe not that much older, but still.... the only actor that looks "youthful" and "boyish" is the one playing Arthur.
