I know Bane's background. I've read the comics. But in the movie, it wasn't Bane who was the child born in the prison, but Talia. And the prison wasn't located on a Caribbean island but somewhere in North Africa, perhaps the Middle East.

An al Ghul climbed out of the "Pit", and I see that as a reference to the Lazarus Pit.

Also, Batman was broken by Bane and believed dead by others. He was thrown into the Pit to die, but he didn't. He rose from the Pit, his body healed. Take that how you will, but I again see the Lazarus Pit reference.

Apparently, I'm not the only one who felt the same. Link below
