Merlin's Revenge - The Grail Wars (DVD)

Many years ago, in a time when the Old Ways of magic were waning, evil sorceress Mab (Miranda Richardson) summoned mighty wizard Merlin (Sam Neill) into existence, giving him the power of her dark enchantments. When Merlin fell in love with the innocent Nimue (Isabella Rossellini), Mab allowed them to be imprisoned by Lord Vortigern (Rutger Hauer). Now, however, Mab has placed a curse on Arthur, the man destined to be King and Merlin, casting aside Mab's dark ways, allies himself with Arthur, determined to help him bring peace to the realm.
