one of the unique aspects of the dark knight is that major action sequences were filmed in IMAX, which is 70mm film run sideways through a camera, as opposed to the standard 35mm. it helped create a much more impressive and immersive experience, particularly if you saw the film in an IMAX theater. the technique has since been employed on inception and mission:impossible- ghost protocol. i was lucky to see both of those in IMAX and yeah, it was pretty dang.
describing their reasoning behind this, wall pfister, asc, told american cinematographer magazine,
