In casting Batman Begins, as with all other aspects of the production, director Christopher Nolan strived to create an epic feel that underscores the film's realism.
Following Nolan's mantra of realism, it was important that every aspect of the Batmobile have a clear purpose
"Chris really wanted the chase to have a loose, raw feel, something somewhere between a modern-day action-chase sequence with all the technology that we use today and something with the raw, gritty feeling of The French Connection," says director of photography Wally Pfister
It was important to Nolan that every piece of Batman's arsenal have a clear and practical purpose. In the film, Bruce Wayne takes a gritty, do-it-yourself approach to developing his tools.
The director also wanted the combat to be more jarring and realistic than graceful "We wanted the fighting to be as realistic as possible."
Nolan's thorough, meticulous approach ensured a consistency of his vision for the film, in which realism underscores every aspect of the ambitious production, from design to stunts to special effects.
Filming at Cardington gave the film a level of realism.
Director Christopher Nolan and fight arranger David Forman (The Last Samurai) were looking to find a style that marries the gritty intensity of street fighting with a disciplined martial arts approach.
