Body Double is a 1984 American erotic thriller film directed, co-written, and produced by Brian De Palma. It stars Craig Wasson, Gregg Henry, Melanie Griffith and Deborah Shelton. The film is a direct homage to the 1950s films of Alfred Hitchcock, specifically Rear Window, Vertigo and Dial M for Murder, taking plot lines and themes (such as voyeurism and obsession) from the first two.
At the time of its release, the film received lukewarm success at the box office and mixed reviews, though Melanie Griffith's performance earned praise and brought her a Golden Globe nomination. Subsequently, it has been better received and is now considered to be a cult film.
