Re: Things you noticed after multiple viewings on DVD / BluRay.
Nolan and/or a casting director cast a little boy named Harry Coles to play one of the young Talia parts. Somehow it never became public during the production and pre- and post-production phase of the movie. We thought there was just one. No one could come up with the name an actor that could have potentially been young Bane but we could have been misled if his name ever came up during that time but it never did.
They cast a boy to play the part of a girl. I guess this part was the part Leilah De Meza was offered before her mom turned it down.
