As other reviewers have duly noted, this film (first released in 1963) is based on the first of four parts of T.H. White's The Once and Future King (1958), focusing on Arthur's birth, childhood, and youth before he became king of England. The film has been reissued as a 45th anniversary edition. It features the well-selected voices of Sebastian Cabot (Sir Ector/Narrator), Karl Swenson (Merlin), Rickie Sorensen (Arthur/"Wart"), Junius Matthews (Archimedes), and Alan Napier (Sir Pelinore). Frankly, I was underwhelmed when I first saw it many years ago and had little patience with the antics. While seeing it again recently, I found the film much more entertaining and frequently charming.
In our family, a film's "acid test" for grandchildren is for them to want to see it again, immediately. After I watched it with several of the younger ones, they requested that but agreed, instead, to check out "Merlin's New Magical Academy Game," passing on the other bonus features. I would not rank The Sword in the Stone among the "classic" animated features produced by Disney (e.g. Bambi, Beauty and the Beast, Dumbo, Pinocchio, and Snow White and the Seven Dwarfs) and Pixar (e.g. Finding Nemo, Ratatouille, Toy Story, Toy Story 2, and WALL-E) as well as DreamWorks' Antz and Shrek. However, how many animation features do?
Perhaps there are other grandparents and parents who also saw The Sword in the Stone years ago, as did I, and are not inclined to have a copy available for children to see. I urge them to reconsider because it possesses a unique "magic" of its own. I think they will also enjoy the bonus features. Hopefully this reissued version will attract the interest and gain the appreciation the film clearly deserves.
