But we made the decision from the very beginning of this project to make it linear - we're pretty strongly dedicated to making the events of each episode unfold in chronological order, and the frame also moves chronologically (though, obviously, along a separate timeline). The existence of the frame is one reason we don't want to mess with the timelines within the story - we already have a parallel structure going on. There is strong resistance to the use of flashback anywhere in this project.
Some of us never agreed to that! The hosts imposed that condition on us (and also the severely detrimental 13 episode per season limit).
Besides, the frame is supposed to make nonlinear storytelling easier, not more confusing. The characters in the frame are there to acquaint the audience with tricky things like that. That's why we have a frame in the first place. If a shift in the timeline is the best available storytelling device for a certain part of the story we want to tell, we should use it. If the frame is interfering with that, I would sacrifice the frame first.
So...what exceptions do we want to make? What stories do we want to tell in flashback or out-of-order in some way?
So far, we have done this in very modest ways. When we planned the opening for Season 2, we stepped back in time to *before* the climatic battle at the end of Season 1, but this time watched the events play out from the perspective of the elves, not the Valar. During the Frame in Season 2, we flashed back to the attack on Celebrían. For episode 3 of Season 3, we stepped back in time with our 'Meanwhile, in Beleriand' episode, catching that story up to 'real time' by the end of the episode. And while the Noldor were traveling through Araman, Finrod had a flashback vision/memory of his parting from Amarië which happened during the rebellion of the Noldor (prior to the Kinslaying). Any I'm forgetting?
I know that for Season 4, we've had a few suggestions of items that we might want to consider telling out-of-order. One is Eöl's story - to do it in a single Eöl-centric episode, showing his history from the end of the great debate at Cuivienen until the arrival of the Noldor. The other suggestion has been how to handle the story of Men being corrupted at Hildorien. I know there is some hesitance about showing the details of a story that Tolkien himself mostly hinted at rather than told...and to avoid retelling the Garden of Eden story. But that doesn't mean we shouldn't at least consider a way to do this.
Any thoughts on this as it relates to Silm Film?
Here are some ideas.
I just listened to session 4.01, where they were all discussing whether to split the events between the rising of the sun and the Dagor Bragollach into one or two seasons. If we don't quite have enough material for two seasons--IMO we have enough material for more than two seasons--we can add flashbacks to flesh out some of our main characters, particularly Beleg, Galadriel, Celeborn, Glorfindel, and Finrod.
We skipped over plenty of time between the departure of the Noldor from Middle Earth and our reintroduction to Beleriand and Thingol's kingdom where we could have created episodes to feature Beleg and Celeborn more strongly. Now that that ship has burned, we still have a chance to make them interesting using flashbacks.
Also, we rushed through the childhood of all the 3rd generation Noldor in Valinor, so there is plenty to flash back towards for those characters as well. Since we want to make Galadriel, Glorfindel, and (presumably) Finrod prominent characters in this series, I'd suggest spending some time using flashbacks to round out these characters as well.
Finally, I wouldn't be opposed to adding a mini-seasons to accomplish some of this. Maybe add a 5 episode mini-season for the adventures of Beleg, Celeborn, and Mablung in Beleriand. It should have lots of action. I'm not sure if a mini-season of life in Valinor would be interesting, though. Shorter flashbacks to life at Tirion High School might be enough to get the gist across.
As for Eol, I don't think his story needs to be told. In contradiction to my usual opinion on matters here, I don't think everything needs to be shown on screen. Eol is weird, and people will get that. Just have him reappear where he first shows up in the published Silmarillion. He's not very interesting and he doesn't need a backstory.
