I had to go and look that up, and yes, at the time of The Hobbit, Gimli was 62, which was considered too young to accompany Thorin (Unfinished Tales p336). But you are off about who was older, as Fili and Kili were 77 and 82.Otaku-sempai wrote: ↑Tue Nov 07, 2017 8:16 pm
Gimli (born: 2879) would have been older than either Fili or Kili, but there's no reason to believe that Aragorn had ever met him before the Council of Elrond. Frodo was born in 2968, probably in Aragorn's fifty-second year in the films. The timeline of the movies raises many questions, some of which are hard to answer. I would just as soon be able to ignore it.
It also looks like Gimli was not introduced to any of the other major characters til the meeting that formed the Fellowship. That means there would be no way to use him in a TV series set before that without screwing with the timeline more than the movies already have.
So established characters who could be part of the series are Bilbo, Aragorn, Legolas, and Gandalf. though Aragorn only if using the movie timeline, since at the time Erebor is reclaimed, Aragorn is only 11-12 years old.
But re-reading on the Wiki about Aragorn's pretty epic adventures between the years of 2956 and 2980, if condensed down to fit the movie timeline, I could see some fast-paced and exciting episodes, if done right.
