Merlin co-creator on series 3

Merlin's co-creator Johnny Capps was recently interviewed by SFX Magazine and spilled some beans about the currently-filming third series.

On the idea that Arthur might some day discover Merlin's secret, he had this to say:

"I think that part of the format of the show is that Merlin keeps his magic a secret, just as Superman keeps his identity secret -- and I think Arthur not knowing about it is the heart of the show. Presumably at some point Arthur would find out, but I think that would be very late on."

On what the third series will cover in general, with the action picking up a year after series 2's finale:

"Within the first five minutes you catch up as to where our characters have been. Camelot has been very focused on the search for Morgana, and Uther has been very concerned about where his ward is. But when she comes back it's very intriguing as to where her allegiances lie and what’s happened to her. She's been on quite a journey."

Capps also confirmed that Emilia Fox will be reprising her role as Morgause (the magical half-sister of Morgana), Excalibur and the Lady In The Lake will feature, Sir Gawain will be joining the action, a Crystal Cave will be discovered, Mark Williams (Harry Potter, The Fast Show) will be playing a "mischievous goblin", and the Great Dragon will have a different role to play.
