What if there was some lost test footage from an unmade version of the Star Wars prequels that never got made?
Things that went into making this look old:
Lift black levels considerably (although I'd do this for any piece tbh)
White and black dust
Matte lines resulting from misaligned optical composites
Separate elements drift a bit despite the "motion controlled photography"
Quite a lot of blur applied to create a very soft image
