About a year before this movie's release, writer, producer, and director Sir Christopher Nolan mentioned he was considering using a mixture of CGI and deleted scenes from The Dark Knight (2008) to have the Joker appear briefly, which Bryan Singer had done to bring back Marlon Brando as Jor-El in Superman Returns (2006). Nolan ultimately decided it was disrespectful to Heath Ledger.
Writer, producer, and director Sir Christopher Nolan said that this movie's theme deals with "pain". For Batman Begins (2005), it was "fear", while The Dark Knight (2008) dealt with "chaos".
(at around 1h 28 mins) According to producers, the line "That's a lovely, lovely voice" was improvised by Tom Hardy.
Tom Hardy, standing at 5'9", had to wear three-inch lifts to make his character Bane appear as tall, or taller than co-stars Christian Bale, Morgan Freeman, and Sir Michael Caine.
Tom Hardy accepted the role of Bane without reading the script. He was verbally told that he would have unprecedented access to extensive stunt training and equipment that he could enjoy knocking around.
