First, and I should have started with this: I think the non-interlaced parts of your trailer, which I assume are tiny pieces of your capture (the color-corrected/non-interlaced part of Luke and Leia swinging by grappling hook/rope?) looks really wonderful. I am very excited about this project.

:there's no point in shooting at higher megapixels, because the
disk space, and rendering time, along with resizing and scaling
make it much harder. also the difference when you render down
to 1080p isn't really that noticeable.
I agree that bit depth is a bigger factor than pixel resolution in this process.
RE: Capturing at 1080p vs downscaling to 1080P - maybe this is true using the method you are using currently? Usually, video downscaled from 4k captures looks signifcantly better.
The only thing I would do differently here, with all of the time involved, as well as this expensive/rare film and equipment, would be to capture it in as high-res a format as possible -at least film-grain resolution- to have the highest quality material to start with. Isn't that kind of the point of capturing the 35mm print in the first place?
