“Everyone has a secret-it's not always written in the face,” declares David Graham (Michael Redgrave), a barely-on-the-wagon father racing the clock to prove the innocence of a son soon to be executed for murder, in this manic, white-knuckle thriller. Redgrave, replete with three-day stubble and shakes from the DTs, cuts an unforgettably fragile figure-wrestling with his own guilt as an absentee dad while trying to connect the dots between a rich auto magnate (Leo McKern, in a furious performance), his long-suffering wife (Ann Todd), mistresses, and chorus girls, as ticking clocks in seemingly every scene count down the hours of his son's life. As in Time's companion film, Blind Date, Losey's (and writer Ben Barzman's) interest in who did it is secondary to the story of who didn't do it, especially since the viewer knows the murderer's true identity from the opening moments. This was the first film to bear Losey's real name since 1951, and his only collaboration with renowned cinematographer Freddie Francis.
