I found the following analysis interesting as to why the concept of warrior Galadriel isn't ridiculous but it just depends on how her character is handled in the new series: A lot of confusion arises because Tolkien only partially sketched in a lot of her backstory and also provided conflicting accounts. However, I now feel more certain that we will see the character develop into the one we recognise from Peter Jackson's depiction. How she becomes 5" taller will probably not be explained. Her father-name was Artanis ("noble woman") and her mother-name was Nerwen ("man-maiden") because of her height and strength. The name Galadriel is the Sindarin version of the Telerin Quenya name Alatáriel, given her by Celeborn, which means "maiden crowned with a garland of bright radiance". So she isn't called Galadriel until she's an item with Celborn. Unfortunately, Morfydd Clark is a little on the short side compared to Cate Blanchett, who's only about 5' 9" herself. However, I'm sure they can use camera tricks as they'll have to do with the Dwarves and Hobbits/Harfoots anyway.
There are different accounts of the gestation period for Elves that range as high as 9 years. I think Tolkien eventually settled on one year. I might shell out for "The Nature of Middle-earth" by JRR Tolkien, edited by Carl F Hostetter, which goes into the minutiae of such details about the lands and peoples of Middle-earth, according to Tolkien's final writings. Part 2, chapter V is titled "Beards". Part 1, chapter XIX is titled "Elvish Life-cycles".
I really like it, it's probably one of top 3 "high-school" themed movies. While it, of course, lacks Jane Austen's characteristic dialogue, I think it shows quite a bit of creativity in translating (most) of the characters and situations in Emma into a high school setting. And it keeps Emma/Cher's character growth into a person who's more appreciative of the people around her and more aware of the effects her actions and words have on others. And personally I'd call it a better movie than the most recent adaptation; Emma. (2020), which, although it had many talented actors in it, was really not a movie I enjoyed. Though personally I'd say the miniseries from 2009 is the best adaptation of Emma.
I thank you can safely assume that her height will not be an issue that the show addresses, much as it wasn't (outside of shots where her dress hide the fact that she was wearing heels as opposed to actually supposed to be bear footed, most of Kates was just cameras at a lower level).
I have a feeling the vast majority of actors who are playing characters in adaptations are not the same height as the character was in the original source material. I mean if you get 5'11'' Brad Pitt in your movie adaption, I can't see him being turned away because the character in the book was 6'2''. Is there some very, very important reason she must be exactly that height down to the inch?
Some of the first reactions are starting to come out, and so far most of them are positive. The biggest complaint seems to be that the pacing is a little wonky in the first two episodes, which all people have seen so far, since it's introducing a ton of different storylines and characters. And for those wondering how Tolkien fans feel, one of the people who posted a positive reaction calls himself "Tolkien Professor" and another person said it felt like it was made for Tolkien fans.
The source material says Galadriel was unusually tall and athletic for an Elven woman - hence the name Nerwen (Man-maiden) given her by her mother. It does not mean she has to be a warrior, of course, but she should appear to be physically imposing in height.
...and dwarf wives should. Galadriel should not look like a short, frumpy hausfrau. Back in the 70s, I thought Julie Christie would be perfect for the role. I even thought New Zealand would offer ideal shooting locations. Thankfully, Peter Jackson had the same realisation regarding the latter and time had moved on regarding casting. Morfydd Clark is to Cate Blanchett playing Galadriel as Susan Hampshire was to Julie Christie playing Andromeda. All fine actors but the replacements couldn't replicate the ideal casting of the originals. We'll see soon enough if I'm wrong. ETA: Catherine "Cate" Blanchett wasn't bear footed? Is Galadriel supposed to be a skin-changer like Beorn? But, yes, she should appear strikingly tall and athletic for an Elven female - just as Tolkien described her. She shouldn't seem like she'd have difficulty seeing over the top of a Dwarf. I don't care if Morfydd Clark has to stand on a box or wear stilts to achieve this provided that she can convey the same ethereal quality as Cate Blanchett.
OK she's presented that way in the books, but is some reason in the story that they are most likely trying to tell in the show that she has to look like. Because really when it comes to an adaptation like this, that's really the only time that kind of thing matters. Just look at Hugh Jackman as Wolverine, he's almost the exact physical opposite of how the character is presented in the comics, but he was still phenomenal id the role, and most people loved him.
We don't have long to wait to see how good Morfydd Clark is in the role. I hope she isn't let down by clunky dialogue as the LotR appendix contains nothing of that nature.
The actor has to be able to sell the character, though. (Not saying that won't happen with Rings of Power.) But as an example, look at Alexander Dreymon (sp?) cast as Uhtred in the adaptation of Bernard Cornwell's Saxon Tales. (The Last Kingdom) Uhtred is supposed to be a bear of a man, a giant blond who can pass as a Danish viking with ease. The actor they cast doesn't only not match that description, he's a pretty-boy who doesn't even come close. He doesn't sell it, at least for me.
