My logic in composing the list:
Tatië has lines in Episodes 2 and 3 (of the Script Outlines). Therefore, I am fine with casting her. IF the Execs are like 'who?' and leave her out of the voting, that is their prerogative. Morwë, Eöl, Nurwen and Tatië are our only Avari 'named characters', so I think she should be cast to round out that group, though obviously hers is a supporting role as 'Míriel's little sister'.
Iminyë has a background role. There are several scenes she may be in, but whether or not she has much of a speaking role beyond (perhaps) expressing surprise over her daughter's interest in Finwë is to be determined. She is in the unique position of having personal experience in what the Hunter does to the captured elves and knowing what it is like to return from Mandos - I can see script writers wanting to use her voice for some scenes. A character who is definitely in multiple episodes can be cast, if we'd like. She should have more lines and screen time than (say) Fimbrethil or Tevildo, and we're casting both of them. Again, the Execs may say 'who?' and ignore her.
Amarië has a non-speaking cameo in Episode 12 at this point. She is also in the next generation that will not be cast at this time, as we have our hands full with the other 30-40 roles that need casting. If we cast her, it will be next time. We will likely flashback to some conversations with her and Finrod in later seasons.
Argon is not confirmed to exist in this project yet. That is a question for Season 3. He *could* be in....but I don't know that. Also, next generation. (Also also, can we rename him not to be #18 on the Periodic Table? Just having someone shout his Quenya name when he dies would be fine with me!)
Eldalotë is not confirmed to exist in this project yet. Technically, she should. She certainly hasn't been introduced on screen yet, as even her husband is not introduced to the audience in Season 2. The entire House of Finarfin plays a background role in Valinor, except for a few scenes with Galadriel. Also, next generation. So, we will deal with her later.
Characters like 'Olwë's wife' or 'Lenwë's wife' exist, and will clearly be seen on screen - but they have no role in the story and may wind up being extras with no lines. Alternately, we might choose to use Olwë's wife more extensively later and decide we need to cast her. But until then...I am not putting her on the list.
I put the list of suggested roles to cast under Trish's post so everyone would know what roles were available to nominate for and start a thread. If no one nominates anyone for a role....obviously we won't cast it. If I left anyone off of the list who should be on it, let me know and I'll edit. If they are in the later generations (Fëanor's and Fingolfin's kids, grandkids, or associated spouses), they are not included on this list because....we have until Friday to complete nominations, and that would be too great a task to do well right now.
