10 Movie Fan Theories EVERYONE Believed
3. John Blake Is Secretly Robin - The Dark Knight Rises
The Theory
The character of Gotham City PD cop John Blake (Joseph Gordon-Levitt) will become Batman's (Christian Bale) trusty sidekick Robin by the end of the movie.
Why Everyone Believed It
On paper, this made total sense: Joseph Gordon-Levitt has a boyishness about him which makes him an easy fit for the Boy Wonder, and considering that John Blake is one of the movie's few original characters, it followed that he would actually be revealed as not-so-original after all.
What Actually Happened
John Blake remained John Blake to the film's ending, even if Nolan couldn't resist revealing his middle name to be Robin in a cute nod to audience expectations.
In fact, Blake ended up inheriting the Batman persona from Bruce, Batcave and all, in the final minutes in the film, seeming to confirm that the Robin namedrop was just a playful joke - though some fans still won't let it go.
