I also found Gilli's voice a bit strange but it is rare to expect really good acting from young people like Harry Melling. I suppose Harry Melling felt a bit awkward to act outside Harry Potter but in Harry Potter, I noticed the same thing in the later films, Harry Mellings voice was a bit strange but I think he was a bit better in Merlin than he was towards the later Harry Potter films. The actors for Percival and Agravaine were fine in my opinion, the only thing I didn't like about Agravaine was the smirk but that was scripted. Tom Hopper in my opinion made Percival a likeable character so he was okay.
