The opening sequence of The Dark Knight uses mobile camera work, parallel editing, and sound to create tension during a bank heist. The camera follows the masked robbers through steady shots and dollies. Editing cuts between teams rapidly to build urgency. Sound includes a fast-paced score and muffled diegetic voices and effects. Mise-en-scene features the robbers in dark suits and disturbing clown masks, contrasting the warmly-lit bank interior with the cool exterior. The final unmasking reveals the Joker, foreshadowing his twisted character.
