"Dark Knight Rises – how did Bruce Wayne magically get to Gotham after he escaped the hole?
1. In an adjacent scene it’s mentioned the bomb will go off in a month, so we can assume that’s how long he has to get back to Gotham.
2. Wayne Enterprises has offices around the world. All he needs to do is get to an office, log in, and wire himself money or supplies to get home. He’s Batman, he can easily do this without being noticed.
3. Batman Begins has a whole sequence of him traveling around the world penniless and nameless. This is a specific skill it’s already established he has.
There are tons of plot holes in that movie, but for some reason people get hung up on the easiest one to explain."
