Strange thing about this trip. So much occurs in pairs. Tennis star Guy (Farley Granger) hates his unfaithful wife. Mysterious Bruno (Robert Walker) hates his father. How perfect for a playful proposal: I'll kill yours, you kill mine. Look how Alfred Hitchcock reinforces the duality of human nature. The more you watch, the more you'll see. "Isn't it a fascinating design?" the Master of Suspense often asked. The original version is an all-time thriller classic. The laying bare of Bruno's hidden nature, along with the great set pieces (head-turning tennis match, disintegrating carousel) and suspense as only Hitchcock can deliver, makes for a first-class trip.
