I can see the beginnings of the "Hitchcock Touch" in The Pleasure Garden. It had touches of a voyeuristic quality shown in some of his other films (Rear Window, Psycho, Strangers on a Train, etc.). I also noticed how the many of the women in the chorus line seemed to be blondes, including the female that the audience member focused on with his binoculars. That specific female type seemed to take center stage in Hitchcock's later films. The short clip was packed full of sinful, or at least questionable behaviors, vices or symbols - lust, gluttony, stealing, policy breaking (smoking in front of a smoking prohibited sign), etc. The film's title, The Pleasure Garden - I took to be inspired by the Garden of Eden, from the Bible, where it is written that Man and Woman (Adam and Eve) committed the first sin of disobeying God and eating from the tree of knowledge.
While there are limitations with the silent film clip (for instance, one can get a lot of meaning from a character's tone), it makes the viewer focus on other qualities - facial expressions and body language of and between characters, and deduct your own meaning from those behaviors.
