Not sure if someone brought this up previously but..
I have been trying to figure out how can JDW character perceive things in reverse and I can only thing of this: He is able to perceive past and present/future at the same time, his mind is somehow able to switch and perceive what he needs at that very moment... To simplify it, imagine you are standing in between two trains, each going opposite direction and each train represents your life and u have the ability to peep into both and see what is happening there... Similar to Cobb's drawing in inception with the circular arrows and line in between but in this case, there are two straight lines going opposite directions and you are in the middle of the process. Not sure how that would work but it's the closest thing I can imagine
I love how Chris Nolan is constantly and simultaneously advocating hard for
(A) photographing on film
(B) seeing films in theaters and
(C) Legitimate IMAX (15 perf, 70mm) all at once in his trailer for TENET.
