The conceptualization of the trilogy started from the imagination; the imagination of many gifted and talented people.
This book shows how the final product, namely the final designs that appear on screen, were first channelled and excavated from the collective unconscious, and how comparing and matching everyone's imagined certain characters and details, to then fine-tune on what 'felt' most 'right'. This is a very special process, one that required a lot of creative power, and the commitment to stay true to Tolkien's world and its essence.
As stated, nailing the general vibe while matching authentic practicality and atmosphere was the result of the contribution of many people making a lot of designs. However, book has 'only' 600 images, about which the author has noted that there existed many thousands of images, and has had to select them. Why? Why shorten the book so much? There are unfortunately only roughly a couple of designs per character or location, which just feels like way too little. I would have loved it if the book were 3 times as long and contained 1500 images instead (within The Two Towers art book alone - and again 1500 in Fellowship and ROTK).
So that's my major complaint: it's too short, and there's too little text to explain the birthing process as deeply as I feel it could be.
If ever a bigger set will be released, I will grab it instantly. For now, however, it's the best thing available that covers this process, and if you are interested in the creation process of the trilogy, these 3 books are a great delight.
Initially, I wanted a book that just showcased majestic pieces of art, not a bunch of "weird looking concept pieces", and, although I still want to look at beautiful art, seeing and reading about how people played with ideas from the books and their imagination, and how they got to the end result, blew me away more than I expected.
If anyone knows of LOTR art books, or has other suggestions, please let me know in the comments or send me a private message.
Thank you and I hope you enjoy your archetypal connection to the wonderful world of Middle-earth and it's denizens and history. I feel that desire, like the sea calling me home.
