It is interesting to observe that in each film, Nolan slips in 2/3 lines of dialogue in a subtle and discreet way that already anticipate or underline his future projects, for example: Interstellar already predicted Tenet, notably during the scene of the discussion between Cooper and Brand after the failure on the Miller planet where Brand says "Time is relative, it can strech or it can squeeze, but it can't run backwards" or the scene of the Tesseract that talks about time in a physical way.
Or of course the Tenet sequence between Priya and the protagonist, which anticipated Oppenheimer.
I already feel that Oppenheimer will leave a clue about his next project after(or not, it's more when he's making his conceptual projects that revolves around time, like Interstellar or Tenet, and less when he's making something outside of his confort zone, like Dunkirk).
