The exceptional depth of discussion on this first topic has me very excited for the next 10 years. Greetings everyone, I am excited to "work" with you! At some point, if a core group of us end up posting regularly, we should strive to get to know one another. The Internet thrives on anonymity, but we can certainly be more personal. My name is Jeff, I live in Chicago, and I have a dog named Mya. She is a trouble-maker, and a far cry from Huan.
Here are my brief thoughts on the three questions Trish posted:
1. I am in the minority that believes Iluvatar should be both corporeal and live-action. It will be very easy to portray that Eru's essence is infinite without keeping it completely abstract: for example, start with a bright point of light coalescing into a throned figure, and use echo effects or an aura to show that it is simply a single manifestation of Eru's power. I also believe we should take some artistic liberty and make Iluvatar female. Tolkien goes out of his way to say the Ainur have no intrinsic gender, but rather that it is simply a function of their disposition, and I see no reason why Eru should be any different. Despite the implied masculinity of the Judeo-Christian deity on which Eru is based, I think a creation myth is more resonant with a female God (the giver of life). It also goes a long way to challenge one of the most common criticisms of Tolkien's work...
2. Everyone else's ideas on the Valar are great, and I have little original perspective to add. I do think they should be normal-sized humanoids rather than giants, however. One of the central premises of Tolkien's work (especially LOTR and Hobbit) is that power and size are unrelated. If we can depict the authority of the Valar without resorting to a physical size difference, we will have done Tolkien proud. We can still make it obvious based on their look and sound that they are a different caliber of essence than the Children.
3. Magic should surely be music, but music can be interpreted broadly as sound. Essentially, I think we stay true to Tolkien as long as we don't have anyone using wands or staffs to cast their "magic." Creation and transformation through spoken word, poetry, song, and instrumental music are all equally resonant and faithful as far as I'm concerned.
Keep up the great work, everyone. And buckle up; it's going to be a long ride!
