As we can see in the image on the left, some of the characters from Batman Begins and TDK will be mentioned - and some may even appear - in this third story. Therefore, screening both of those earlier films prior to seeing the latest installment could prove invaluable to understanding the new story and the characters.
TDKR attempts to wrap up the trilogy and does address many of the story beats and ideas presented in its predecessors. It also develops many of the characters that were previously introduced.
Since the series is set up as a trilogy, knowing where it started is pivotal in appreciating how it ends.
Accordingly to early reports, TDKR features 100 minutes of action sequences and much of the movie was shot using IMAX cameras. With that in mind, the best way to view the film is most likely on a 70 mm IMAX screen.
As Screen Rant's Kofi Outlaw previously explained, "you aren’t really getting 'the full' IMAX experience – especially the one Chris Nolan intended – without that 70mm IMAX theater. 70mm is the only way you will be able to see everything that Nolan shot on IMAX cams."
So even if it's out of your way, driving to see the movie the way that it was intended to be screened would be preferable to seeing it on a digital IMAX screen (or a regular one).
This year, we have been treated to several big-budget superhero films like The Avengers and The Amazing Spider-Man. Both of those movies sought to honor their source material in a fun and entertaining fashion.
