Oh man, I really don't want to see any artificial hairs or dirt in the image of "Star Wars". That is just going way too far in my opinion and would cause me to lose all interest in this otherwise fantastic project. Adding artificial elements such as this is dangerously close to Adywan territory in my opinion, and I'm not fan of his editorial decisions.

I don't want to go back over the subs shake thing again (I stand by all the statements I made previously), but in a true restoration using film elements, you are trying to bring out the original version intended by the filmmakers. In your case, you want to replicate what it looked it originally, but in its best presentation possible. No professional restoration job would actually add elements such as dirt and hairs though, that's the opposite of preserving the best possible image. You want to go for how the film looked in a theater on opening day, not how it looked three months after it's initial release after the print had been played endlessly. The only times I see hairs and dirt tossed into a film artificially are for films like "Grindhouse" where they are going for a distinctly dated retro look in a campy sort of way. I don't think "Star Wars" should be treated like that.

If you do decide on fake dirt and hair, etc.. I hope you would at least consider a version that doesn't include those elements. As for the grain, I think the fine grain level is perfect as it is. These transfers thankfully preserved a fair amount.
