Blow Out - Themes and Allusions

Themes and Allusions

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.

As with several other De Palma films, Blow Out explores the power of guilt; both Jack and Sally are motivated to help right their past wrongs, both with tragic consequences. De Palma also revisits the theme of voyeurism, a recurring theme in much of his previous work (for example, Hi, Mom!, Sisters, and Dressed to Kill). Jack exhibits elements of a peeping tom, but one who works with sound instead of image.

Blow Out incorporates multiple allusions both to other films and to historical events. Its protagonist's obsessive reconstruction of a sound recording to uncover a possible murder recall both Michelangelo Antonioni's film Blowup and Francis Ford Coppola's The Conversation. The film alludes to elements of the Watergate scandal and the JFK assassination. The film also recalls elements of the Chappaquiddick incident, although De Palma intentionally tried to downplay the similarities.

De Palma also explicitly references two of his previous projects. At one point in the film, Dennis Franz watches De Palma's film Murder a la Mod on television. Originally, the character was to watch Coppola's Dementia 13, but Roger Corman demanded too much for the rights. A flashback where Travolta recalls an incident where his work got a police informant killed was also taken from an abandoned project, Prince of the City, which was ultimately directed by Sidney Lumet.
