The Skyfall trailer creates tension through unexpected scenes like Bond falling to his death and dark lighting when he is alone, contrasting brighter scenes when he teams up. Non-diegetic sounds like the gunshot that kills Bond heighten the tension. The Avengers trailer starts with ominous narration and scenes of police responding to a mysterious threat. It introduces the villain Loki through quick cuts and increases pace through action clips of the heroes arguing and battling together. Both trailers use editing techniques like continuity cuts and changes in pace to generate suspense around their plots and main characters.
