Thematically, "Blow Out" almost "exclusively concern the mechanics of movie making" with a "total, complete and utter preoccupation with film itself as a medium in which ... style really is content." In numerous scenes, the film depicts the interaction of sound and images, the manner in which the two are joined together, and methods in which they are re-edited, remixed, and rearranged to reveal new truths or the lack of any objective truth. The film uses several of DePalma's trademark techniques: split-screen, the split diopter lens, and the elaborate tracking shot.
