One of many things I love about Hitchcock movies is the use of terrific camera work -- a scene so clever or well-shot that I stop to appreciate it regardless of how engrossed I am in the storyline. The best example would be the "Strangers on a Train" scene where Farley is playing a tennis match, and you see the crowd's gaze moving left to right, following the ball, all except for Bruno, who's staring at Farley. Creepy.
In "The Lady Vanishes," I thought the standout moment was when the noise in the train picks up, and Miss Froy slowly traces her name on the train window. Iris had just woken up, and Miss Froy was babbling about her million Mexicans, and all that context made me think on first viewing that the scene was just a dream. It was an interlude into the surreal part of the film, and I found the camera work to be clever.
