I would personally start with a smudgers version of the first TCW movie, without the long introduction (the first part of the story is really boring and irrelevant, i mean the mission where anakin Goes to Christophis) centered on the battle of the planet itself with introducing Ahsoka.
Yeah, I’m looking at exactly this at the moment. Anakin needs to meet Ahsoka on Christophsis right at the start of the show, and it makes a load of sense to start with the Domino squad arc which really leans into clone culture in such a clone-heavy show. I think it’s neat. But I’m still going to query which elements need to be retained, and whether or not it is right to interlace these two arcs. It might be that our episode one is Christophsis and our episode two is Domino squad. Or that I produce a lightly or extremely lightly edited version of Smudger’s.
This is certainly going to be one of the biggest challenges of the project - when is it best to combine content, and when is it best to leave it separate? Leaving it split gives basically just a slightly polished version of the original presentation, whereas combining things can result in the problems other editors have encountered when moviefying things. The answer must be simply ‘do whichever is best to make a good episode narrative within the broader show structure’, but getting that right is going to be hard.
For example, Cat and Mouse, which is the first episode of the Christophsis arc, introduces some interesting things. It shows Anakin meeting Yularen - but do we care? It shows Trench being quite competent, and he shows up a couple of times near the end of the show - but do we care? It also features our first appearance in the show of Bail, doing good works, which’ll lead nicely into his appearance in the formation of the rebellion in Ep3 - but do we care?
