This is an entertaining thriller that reveals the power of at least one underappreciated artist. I'll admit I thought of Don Johnson as the pretty boy from Miami Vice, but in this film he shows range. As the character demands, he goes from boyish charm without empathy to narcissistic rage when anyone tries to deny his whims. Scary.
Rebecca De Mornay has been greatly appreciated for the films of the 1980s and 1990s in which she played roles both heroic and villainous, and she continues to work, most recently in the TV series, Jessica Jones. She has star power here, playing a character more given to fight than flight.
Director Sidney Lumet is in full Hitchcock mode, which is generally a good thing. He photographs De Mornay as Hitchcock famously photographed the blondes in his thrillers. There is more than one back-of-the-head shot and several moments when De Mornay is frozen in terror while we hear Johnson off-screen threatening her. Unlike Hitchcock's blondes, De Mornay's character is in full attack mode from start to finish.
Although screenwriters are generally underappreciated, one aspect of this film made me look up the name Larry Cohen. The moments I found most chilling often come from a line of dialogue, delivered simply, in keeping with the scene. These lines reveal the next twist in the villain's scheme. No underscoring, no camera work, no "action," just story. Perhaps this is not surprising from a writer quoted as saying, "Many of the A-movies are long forgotten. They're boring, slow, and tedious. The B-movies are fast-moving, exciting, and energetic."
