Christopher Nolan himself describes Tenet as his biggest movie ever, a quantum cold war film that is based on the world of international espionage.
If Tenet performs well in theaters, studios will see that as a signal to release their long line of blockbusters that are currently placed in cold storage.
As such, Tenet will allow movie studios to gauge the interest of audiences by revealing whether or not they are willing to go to theaters to watch the film on the big screen.
In effect, Nolan is increasingly being seen as the poster boy for blockbuster filmmaking who can do no wrong.
