If you end up being able to remove even the TIEs, I would consider whether the later conversation about lightspeed skipping will make sense.
I feel that if you see the Ties before the cut it’s an edit mid scene so it has to be either before you see them after the wall break or keeping the lightspeed scene.
I’ve now got 3 different versions of the movie that I’m working on as I have so many ideas but every time I watch a final cut I just come up with more. I’m losing it a bit Haha!
