That perspicacious wizard, Merlin (Sam Neill), takes center stage in this made-for-TV retelling of the legend of King Arthur and his court. As the king’s right-hand man, Merlin tries to protect Arthur as he gains Excalibur and constructs Camelot. Meanwhile, he suffers the betrayal of his wife, Guinevere (Lena Headey). John Gielgud, Helena Bonham Carter, Rutger Hauer and James Earl Jones also cross lances in this medieval epic.
