Hitchcock’s films usually centre on either murder or espionage, with deception, mistaken identities, and chase sequences complicating and enlivening the plot. Three main themes predominate in Hitchcock’s films. The most common is that of the innocent man who is mistakenly suspected or accused of a crime and who must then track down the real perpetrator in order to clear himself. Examples of films having this theme include The Lodger, Strangers on a Train, I Confess, To Catch a Thief, The Wrong Man, and Frenzy. The second theme is that of the guilty woman who enmeshes a male protagonist and ends up either destroying him or being saved by him; examples of this theme include Blackmail, Notorious, Rebecca, Vertigo, and Marnie.
