Found on the movies IMDb trivia page.
These are things that are interesting that I had not noticed......and thought you guys would also like to know. Lots of nods to comics and stuff I did not know at all, or had totally missed. My comments are in brackets.
- 5'10" Tom Hardy had to wear 3 inch lifts to make his character Bane appear as tall or taller than fellow co-stars Christian Bale, 'Morgan Freeman', and Michael Caine. (For those complaining about him being shorter than Bale).
- When Selena Kyle disappears from a rooftop, Batman's remark "So that's what that feels like" is lifted directly from the Kingdom Come graphic novel. Even the circumstance is similar.
- During the motorcycle chase scene Bane is wearing a red helmet with black visor as well as a brown motorcycle jacket. This is the original costume Jason Todd took under his Red Hood persona, which is itself a callback to The Joker's original criminal identity. (An unintentional one but a joker reference nevertheless)
- The Pit Prison where Bruce Wayne is imprisoned after his initial encounter with Bane is stated to have originally been a place where plague victims were sent to avoid contaminating the population. In ancient times, such places were known as Lazarettes, referring to the famous Biblical leper Lazarus, whom Jesus raised from the dead. This is a literalization of the Lazarus Pit, which in the original Batman comics is where Ra's Al Ghul bathes to keep his also literal immortality. Thus, when characters escape the Pit Prison in the film, they are said to have "risen." (So it was the lazarus pit afterall, a nolanised one)
- Christopher Nolan recreated much of Bane's costume and overall appearance. Notably, Nolan removed the full-face mask, which he felt make him look too much like a Pro Wrestler. Nolan felt Bane's comic book costume would come across in the film as too cartoonish, and wanted to avoid comparisons to the adaption of Bane in Batman & Robin.
- When Bane rips the photo of Harvey Dent in half he does so vertically through the middle of Harvey's face replicating his transition to Two Face at the end of The Dark Knight. (How Did I miss this)
- The character Barsad, Bane's right-hand-man played by Josh Stewart, is a sniper and heavy arms expert. He is always shown wearing a bulletproof vest which has large bullets on it and a red scarf. This is a take on the Batman villain DeadShot, a character which co-writer David S. Goyer had expressed interest in bringing to the big screen. (How was this missed, haven't seen it mentioned on the board yet)
- The quote that Commissioner Gordon reads over Bruce Wayne's grave comes from the ending to Charles dikkens' novel A Tale of Two Cities. It is said by Sidney Carton as he willingly sacrifices himself to the guillotine in place of Charles Darnay, the husband of the woman he loves. As Carton ascends the steps of the guillotine, he imagines a Paris reborn by revolution. The novel, which takes place during the French Revolution, shares a theme of class conflict with The Dark Knight Rises (Posting it since there have been a few posts asking about this)
- Christian Bale and Michael Caine spent several weeks filming exterior shots of Wayne Manor at Wollaton Hall, Nottingham, but the director Christopher Nolan just used one shot of Bale as Batman in silhouette on the roof and one shot of Caine at the graveside. (More Alfred, and more deleted scenes, perhaps even a nod to a longer cut, that we will never know of)
- At the end of the movie when Blake (played by Joseph Gordon-Levitt) is exploring the Batcave, his black jacket has a blue stripe that dips in the middle on the back of it. This is very reminiscent to the character Nightwing, who the first Robin eventually became. (I must have missed this, and to answer all questions then, John Blake, or rather Robin becomes Nightwing, as he did in the comics)
- Bane has a triangle shaped scar on the side of his head, most visible during the stock exchange scene. Miranda Tate has an identical scar on her back, noticeable during her love scene with Bruce, thus hinting at her membership in the League of Shadows and true identity as Talia. (Totally missed it)
- When the prison medic finally tells Bruce Wayne the full "myth" of the prison's lone escapee, he refers to Ra's al Ghul's child as "the daughter" a single time. This and the child's actual appearance are the only plot elements that foreshadow the revelation that Talia, not Bane, is the child. (I am not sure he does, but if he does, how did everyone miss it)
