I know Alfred Hitchcock over under sideways down, and yet this essay, assembled by the brilliant Nerdwriter, opened my Hitchcock windows and got me excited in a new way. The focus is on an early scene in Vertigo that I had always regarded as an exercise in rote set-up and exposition. But there’s more to it than that. “It’s a dance,” Nerdwriter observes. “[And] it holds up the rest of the film.” Definitely worth watching.
