DC Comics has had incredible success with their big screen adaptations, from Christopher Nolan's The Dark Knight trilogy to the more contemporary "Synderverse," where leading characters like Aquaman and Wonder Woman are the stars of the show. It's not just the heroes that make these movies so popular, though. DC's villains drive the action-packed plotlines, and one of the things that makes them so sinister is the foreshadowing tucked away in their stories. You may not have noticed, for example, that the scar General Zod gets in Man of Steel ends up resurfacing on Doomsday in Batman v Superman: Dawn of Justice. There is also foreshadowing in the background details, like when Ludendorff seems to grow a pair of "horns" while talking to Diana in Wonder Woman. Sometimes these little previews are even subtly placed in dialogue. When Bane describes his backstory to Batman in The Dark Knight Rises, he actually provides information that lets us know he's not the child that escaped the prison pit.
If you love discovering little clues on the big screen, check out this list of foreshadowing details from DC movies.
In Wonder Woman (2017) when sir Patrick sees Diana in parliament he reacts strongly. You are meant to think that he is reacting this way because she is a woman in a place for men. He is really reacting like this because he recognizes that she is the Godkiller sent to destroy him (Ares).
At the end of Batman Begins, Batman receives a joker card from Jim Gordon. This card was recovered by a policeman named J.Kerr, a common alias of The Joker.
In the movie we are led to believe that the child that escaped from the prison was Bane as a child because the story kept reminding us that Bane was born and raised in the prison.
BUT earlier in the story Bane says his famous quote: "... I didn't see the light until I was already a man..." They foreshadowed the fact that the child isn't him because the child "saw the light" while still a child.
