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.
Bruce Wayne's doctor visit in which the doctor lists off all the degenerative injuries to his body (lack of cartilage, scar tissue, etc.) and the use of a mechanical knee brace both are reminiscent of Kingdom Come, where an older Bruce Wayne requires the use of an exoskeleton to move due to years of physical wear and tear on his body.
This is the only live-action "Batman" film where the Bat-signal is never used.
This movie marks the first time in a live action Batman movie that Batman appears in daylight.
SPOILER: Marks the first time where actor Cillian Murphy has not worn some sort of a cloth or burlap bag on his head, in a film directed by Christopher Nolan.
SPOILER: The coloring and shading of the cloth draping the Batman Memorial Statue during it's unveiling was similar to the blue colors of Batman's costume as traditionally seen in the comics.
SPOILER: In addition to the numerous elements from the "Knightfall," "The Dark Knight Returns," and "No Man's Land" storylines, the film also borrows from the "Legacy" storyline, which involves Bane becoming Ra's Al Ghul's successor and plotting with the League of Shadows to destroy Gotham City.
