Interesting we are talking about the age of the
hobbits in the movies. Something that never bothered me (which is a bonus for PJ), the only thing that bothered me about the hobbits is that I really didn't like Elijah Woods as
Frodo.
But there was another age issue that did bother me, the
elves.
Cate Blanchet and Hugo Weaving were great in their roles, but they didn't look at all as I expected
Galadriel and
Elrond look.
by the time of LOTR, Elrond was over 6500 years old, and Galadriel much older, however elves don't age, or age very, very, very slowly. I would have expected them to look much younger, like the way
Legolas,
Haldir or
Arwen looked. Elrond clearly looked older than Arwen but he didn't, maybe they wanted to clearly show the father-daughter relationship but that's not what
Tolkien said.
Anyway, it bothered ME, not necessarily a big deal.
I must add that since the movies are a visual representation of the stories, the actors portraying the characters should look as close as possible as Tolkien described them.
In one of my multiple "I am bored" moments, I asked ChatGPT to cast Idril and
Luthien based exclusively on looks (not necessarily about beauty but looking like Tolkien described them as well as fitting their personalities)
After a bit of tinkering the verdict were
Luthien: Alexandra Daddario
Idril: Florence Pugh.
What's your issue with Elijah Wood?
I know the question isn't directed to me. But I too have issues with that casting.
I said it before, and this can be totally a personal view, but I would like the actors portraying the characters to not only act well, but to look like the image I have of them from Tolkien.
That's why I didn't like Cate Blanchett as Galadriel or Hugo Weaving as Elrond, they looked too old and as elves they would look younger.
Back to Frodo, one problem was that he looked like a teenager, younger that the other 3 hobbits although he was the oldest.
Second, and this is not Elijah Woods's fault, I didn't like the frequent screaming, but that's just me.
On the positive side, I think some characters portrays were great:
Gandalf,
Saruman,
Boromir.
Faramir looked like Faramir but didn't act as Faramir.
Of course the best cast in the entire trilogy was
Gollum.
Worst:
Sauron (the eye).
