Six sequences, including the incredible truck-flip (achieved without CGI), were filmed in IMAX 70mm format. With an aspect ratio of 1.43:1, these scenes occupy the full IMAX screen, though the majority of the film was shot on 35mm and is framed at 2.4:1.
I saw The Dark Knight at the Krungsri IMAX cinema at Siam Paragon in Bangkok. The IMAX cinema at Major Cineplex Ratchayothin in Bangkok also has a 70mm projector, though its screen is slightly smaller.
