In the eighties I remember a movie about a young boy who realizes that he is a wizard or he gets some kind of ring that gives him powers. I remember a castle that he goes to. I also remember him going to a forest and there was a woman in a tent that suduces him and then she turns into a big bug and he kills her. If any one can help it would be appreciated.
