Merlin: Series 4 Confirmed for October
The BBC has announced that Series 4 of Merlin will begin early October on BBC1. The day and time are still to be confirmed but it will begin sometime in week 40 (1-7 October). Merlin traditionally airs on a Saturday, but with the Doctor Who Series 6 finale showing early evening, it’s not clear if that will still be the case.
Details on the opening two-parter, The Darkest Hour, follow.
BBC One’s Merlin returns, with a thrilling two-part opener to the new series.
Merlin faces his toughest challenge yet when Morgana’s blinkered determination threatens not only Arthur’s future, but also the very balance of the world. With her magic stronger than ever, the sorceress summons the mighty Callieach to tear open the veil between the worlds.
Hellish creatures pour forth, killing all who succumb to their touch. With Uther a shadow of his former self, it falls to Arthur and his loyal knights, including Lancelot, to protect the kingdom.
But it will take more than just swords to vanquish their enemy and Merlin is shocked to the core when he discovers the only way to restore the equilibrium requires a sacrifice of unimaginable proportions…
Colin Morgan plays Merlin, Katie McGrath plays Morgana, Bradley James plays Arthur, Gemma Jones plays Callieach, Anthony Head plays Uther and Santiago Cabrera plays Lancelot.
Merlin also stars Richard Wilson as Gaius, Angel Coulby as Gwen, Nathaniel Parker as Agravaine, John Hurt as the voice of The Dragon, Tom Hopper as Sir Percival, Eoin Macken as Sir Gwaine, Adetomiwa Edun as Sir Elyan and Rupert Young as Sir Leon. Emilia Fox guest stars as Morgause.
