Although Invasion can be interpreted in interesting ways along psychological and feminist lines, its importance as a text has centered primarily on political and sociological readings. In his introduction to this volume, Al LaValley explores the politics of the original author of the magazine serial story on which the film is based. Jack Finney; of the film's producer, Walter Wanger; of its director, Don Siegel; and of its screenwriter, Daniel Mainwaring. And he looks at the ways the studio (Allied Artists) tried to neutralize certain readings by tacking on an explanatory frame story. The commentary section includes readings by Stephen King, Peter Biskind, Nora Sayre, and Peter Bogdanovich. A section of postproduction documents reproduced here (many for the first time) includes many written by Wanger and Siegel. The volume also contains two previously unpublished framing scripts written for Orson Welles. For students and individual enthusiasts, the contextual materials are particularly interesting in showing how crucial the postproduction history of a film can be.
