The Dark Knight has a slew of awesome gear in the Christopher Nolan universe, including a periscope in the franchise reboot, Batman Begins. It is this piece of tech that lets us get from Batman's Gotham to Game of Thrones' Westeros in just one move.
How did I only just realise this?!
Turns out that the kid who plays everyone's least favourite king, Joffrey (Jack Gleeson), also plays the Little Boy who Batman gave his periscope to as proof that he'd met the caped crusader in Batman Begins.
