He's talking about the characters. If we go by your definition, there hasn't been a single authentic movie ever... even those 'Based on a True Story' ones.
Probably just a more grounded premise and setting in those first two, along with Jackie Brown they all used retro culture and criminality to reinforce themes about adult inertia and deflated ambition. He probably hit a fork in the road then and realized studios would develop genre-bending in earnest, so then he started doing feature length period satire.
Love the trailer, looking forward to it. Looks like Russel's bounty hunter has Leigh and the others might have been on her trail as well with one being something else entirely.....
70 mm film (or 65 mm film) is a wide high-resolution film gauge for still and motion picture photography, with higher resolution than the standard 35 mm motion picture film format. As used in cameras, the film is 65 mm (2.6 in) wide. For projection, the original 65 mm film is printed on 70 mm (2.8 in) film. The additional 5 mm are for 4 magnetic strips holding six tracks of sound.
