Two Famous Hitchcock Villains in One Movie
To me, "ffolkes" is notable because it has the only appearance of two great Hitchcock movie villains facing off in the same picture:
Anthony Perkins (Norman Bates from "Psycho")
vs.
James Mason (Cary Grant's spymaster adversary Vandamm in "North by Northwest")
Mason is a good guy in this one, however.
The two actors get a scene or two together, and it is great to hear their voices, see their faces, in juxtaposition, given that they represent two of the greatest Hitchcock villains ever.
