1. Hitchcock Touch: The high-angle shot as the dancers enter the stage. We can see the producer watching the dancers. We can see all the way across the stage into the orchestra pit. A very stylish shot - most of the silent films I've seen are much more "stagey" and static.
2. Certainly, Hitchcock's great sense of humor comes through in this sequence. When the dancer hands the man her curl of hair and the no smoking sign have a very Hitchcockian sarcastic tone.
3. The story was told clearly and effectively without the use of dialog.
