Body Double is writer/director Brian DePalma‘s homage to classic thrillers by the master, Alfred Hitchcock. The tributes to films like Vertigo, Rear Window, and Dial M for Murder are so prominent, some have suggested that Body Double itself is a quasi-remake of sorts.
Whether it is or isn’t doesn’t matter—Body Double is, ultimately, a great film, a violent, lurid piece of cinema that still holds up to this day. The trailer posted above is a classic, having won a Clio in 1984. It doesn’t show anything that actually happens in the movie, so here’s a plot summary for you, courtesy of The Database:
After unemployed actor Jake Scully finds his girlfriend in bed with another man he moves out and accepts an offer from fellow struggling actor Jake Bouchard to house-sit for a few weeks. Apart from getting to live in a swank and ultra-modern house he also get to watch a sexy neighbor, Gloria Revelle, who does a sexy dance in front of her window every night at exactly the same time. He becomes interested in the girl, infatuated even, following her around and eventually meeting her. She also has another admirer however and while watching her one night through his telescope, Jake sees her murdered by this other man. The police are skeptical about what he claims to have seen, but the case takes an even stranger twist when, while watching adult TV, he sees a porn star do the exact same dance he’d watched for all those nights. He soon realizes he’s been an unwitting accomplice in a complex plot.
