UPDATE - The Alvarr casting has turned out to be a foiler. Joseph Mawle hasn't been filming after all.
A couple bits of casting news for the opening two parter.
Actor Joseph Mawle will be reprising his role as Alvarr in Merlin’s fifth series. He is set to appear in the opening two-parter.
Given the character owes Morgana a bit of a favour, it seems likely he will be teaming up with her.

I literally couldn't ache anymore if yesterday I spent 5 hours in the gym. Instead I had a sword fight in a forrest dressed as a saxon...— Matthew Prowse(@Matthew_Prowse) March 24, 2012
Thinking about it, being sat in make-up and having Bradley James one side and Rupert Young the other I did feel quite special #Merlin— Matthew Prowse(@Matthew_Prowse) March 27, 2012
