Alfred Hitchcock's Cameo Appearance
In what became his signature, director Alfred Hitchcock makes a brief appearance near the very beginning of the film. Just after his own directorial credit appears on screen, he is seen trying to catch a city bus, only to have the doors slam in his face. This playful cameo allowed Hitchcock to insert his authorial stamp and engaged audiences who made a sport of spotting him in his films.
The Boy Covering His Ears
In the Mount Rushmore cafeteria scene, just before Eve Kendall 'shoots' Roger Thornhill with a blank-loaded gun, a young boy in the background can be seen plugging his ears in anticipation of the loud noise. For years, this was considered a continuity error. However, many analysts now believe it was a deliberate 'meta' joke by Hitchcock, winking at the audience by having a character on-screen acknowledge the artifice of the staged shooting.
