Part 8 is about Coruscant (briefly) as it moves onto costuming and touches on what an Assistant Director does on a Star Wars set.

A shorter Part 9 covers the climactic Gungan/Droid battle. There was a lot of work here to merge two different VHS recordings with different framerates and subtitles, as well as upscaling it and editing it together with some other footage from the DVD/Blu-Ray.

Full running time right now is 3hr 27min. Final length I have to assume is around maybe 3:50, maybe more.
It seems light Part 10 will be lightsaber dueling and training, while Part 11 may be editing and deleted scene talk. The final Part 12 I’m thinking will be about wrapping up the film, some final interviews and the release of the film with some early Episode II talk about what it could be.
