With all the dragons, swords and sorcery you would expect from a fantasy series, Merlin tells the story of the rise of the legendary wizard during his teenage years. It stars Colin Morgan as young Merlin, Bradley James as Prince Arthur, and features Anthony Head — Buffy the Vampire Slayer‘s Rupert Gilles — as King Uther Pendragon.
Each season includes 13 episodes. NBC already aired Season One in the U.S., on Sunday nights last summer. Syfy will air those episodes in a special marathon event on Sunday, March 28, before premiering Season Two alongside SGU starting April 2.
Syfy has not announced yet whether Merlin will air in Santuary‘s 10 p.m. time slot, or if the more kid-friendly show will run earlier in the evening — making for a possible move for SGU to 10 p.m.
Merlin airs on BBC One in the United Kingdom, where its second season wrapped up in December.
