Yes, it's a king Arthur story, but it's mainly about Merlin, hence the name of the film. But that what makes it a great film, you get to see all of Merlin's life, from birth to… well, no exactly death, since he's a wizard… I better not spoil the end…

Samuel Neill plays Merlin, the sorcerer, and Miranda Richardson plays the pagan priestess, Mab. She also does the voice for the Lady of the Lake. The cast also contains Helena Bonham Carter, Martin Short and the voice of James Earl Jones for the Mountain King. In front of Merlin's eyes, Arthur (Curran) grows up and pulls Excalibur out of the stone, like the original legend. But before Arthur, Merlin lives his own life. At a young age, he falls in love Nimue (Rossellini), but his love does not stop for her even at an old age. He goes through many struggles with many kings, but finally Arthur is his success.

I got this movie when I was pretty young, and my family and I have also liked this movie. So you should go find it and see it. Yeah, it's worth-watching!
