Walk km 17,754-17,765: Stanley Park
TV Episode #125: Suspicion - 4 O'Clock (1957, Alfred Hitchcock)
TV Episode #126: The Rebel - Panic (1959, Irvin Kershner)
A couple of big names here. Alfred "Psycho" Hitchcock and Irvin "The Empire Strikes Back" Kershner.
The big difference here is that the Hitchcock episode was based on a short story by Cornell Woolrich. Hitchcock is the better director but any story by Woolrich is bound to be interesting no matter who directs.
