Last year at Unplugged Expo 2 Roland Parliament, voice director for the first 65 episodes of Sailor Moon and the voice of Melvin, announced that he would be releasing a book about the dubbing of the show. Sailor Moon Relections, the inside story of the original recordings of the English version of Sailor Moon, is nearing completion. In order to be published it needs pre-orders, which you can put in now by mail or through Pay Pal. Information about this pre-order can be found at Moon Chase. A hard copy of the book will be $20 for softcover and $30 for hardcover. There is also a $4.99 ebook option which does not require a pre-order.
You can also check out Moon Chase to see excerpts of the book which include a foreword by Terri Hawkes, the voice of Sailor Moon.
