Merlin's Colin Morgan reveals celebrity guest-stars for series 3

Merlin star Colin Morgan was interviewed by USA Weekend and revealed that Warwick Davis (Willow, Harry Potter) will be appearing in the third series, along with Miriam Margolyes (in episode 6). Santiago Cabrera (Heroes) will also reprise his role as Lancelot. Filming of the fantasy drama started in March (with production moving to France on 8 April), aiming for a probable autumn premiere. This will also be the first year Merlin's been shot in HD, in line with the BBC's policy of moving the majority of its drama into high-definition ahead of BBC1 HD's autumn launch.
