The only episode of The Alfred Hitchcock Hour directed by Hitchcock himself (though he'd previously helmed several of the anthology's half-hour installments), "I Saw the Whole Thing" draws its suspense from the reliability -- or lack of reliability -- of eyewitness testimony. Arrested on suspicions of causing a fatal car accident, mystery writer Michael Barnes (John Forsythe) insists upon acting as his own attorney. Five witnesses insist under oath that they saw Barnes run a stop sign -- and in each case, Barnes discredits their testimony by proving that the witnesses only thought they saw what they saw, based on their own experiences and personal prejudices. Things take an unexpected turn when a sixth witness offers a sixth version of the accident.
