Based on the Classic book (Gavin Maxwell-Ring of bright water.) The film is a warm,family tale,that is loosely based on the book. It has a great feel and atmosphere,mainly because it was filmed on location in London and the Highlands (although not the real locations )The acting,as you would expect from the cast,is great. They have a real feel for the wildlife. By the way,this film was the last that the author,Gavin Maxwell ever saw. He was dying of cancer at the time,and went to see the film,in great pain. He thought it was great,crying at the scene of Mig's death. By the way he had no contact with the films producers. I would recommend the film,as an introduction to the books,not as a substitute to them.
