What if?
The largest energy supplier is formed as a result of the events in INCEPTION. That energy company helps lead to innovations that create the technology enabling space travel through a wormhole in INTERSTELLAR. And the world that exists after the events of Interstellar enables the inversion of events that unfold in TENET.
The theme of INVERSION in the Nolan Trilogy?
IN
Tenet (2020)
A twilight world of international espionage engaged in a mission combating with and against the INVERSE effect of events.
IN
Interstellar (2014)
A team of explorers travels through a wormhole in space (an INVERSE of space) in an attempt to ensure humanity’s survival.
IN
Inception (2010)
A thief who steals corporate secrets through the use of dream-sharing technology is given the INVERSE task of planting an idea into the mind of a C.E.O.
What if?
The movie TENET is about reversing things in INCEPTION to ensure dream-sharing technology never exists, due to the world ending events it leads to in INTERSTELLAR and the post-interstellar travel effects which cause the world that exists in Tenet, based on my speculation or theory.
This crossed my mind when watching the TENET trailer, and thinking back on how similar these 3 films all are.
They all involved the theme of inversion as I explain in the post above, and they all involve teams of people working together to accomplish an extraordinary task which all can be connected i.e., Dream Technology to Interstellar Travel to the Reverse Effects in Tenet.
