What director Kenneth Branagh and playwright-turned-screenwriter Harold Pinter have done to 1972's suspense drama "Sleuth" isn't so much remake it as remix it. The new version is a shiny piece of hardware that might as well be called "Sleuth 2.0," and it's exactly what you would expect from Pinter: very clever, extremely cold. Maliciously entertaining, too, until the halfway point, when you suddenly start wondering why anyone should care.
The original film, directed by Hollywood legend Joseph L. Mankiewicz from Anthony Shaffer's hit play, was pure gimcrackery: a two-character, two-act fake-out about headgames turning lethal. It starred Laurence Olivier as an aging crime novelist and Michael Caine as the younger actor in love with the older man's wife, and it stuck defiantly to the source's one-set, real-time structure.
