Body Heat (1981)

Synopsis
Lawrence Kasdan's first directorial effort is a throwback to the early days of film noir. The scene is a beastly hot Florida coastal town, where naive attorney Ned (William Hurt) is entranced by the alluring Matty (Kathleen Turner in her film debut). Ned is manipulated into killing Matty's much older husband (Richard Crenna), the plan being that Ned's knowledge of legal matters will enable both conspirators to escape scott-free. This might have been the case, had not Matty been infinitely craftier than the cloddish Ned. Just when it seems as though the film has run out of plot twists, we're handed yet another surprise. ~ Hal Erickson, All Movie Guide
