In the movie Psycho an example of irony I found was when Marion's sister went down into the fruit celler and saw Norman's mom. I thought the mom was going to turn around and stab Lila, but it turns out she was dead this left me confused. This is situational irony because through out the whole movie we never saw face it was so well hidden with the camera angles Hitchcock used. This is ironic because we saw mom kill two other people so we expected her to jump out the chair and kill Lila but no.
     This left the audience confused because if mom didn't kill Arbogast and Marion who did? It turns out the whole time it was Norman dressed up as mom which really explained some of scenes in the movie like how mom can move so fast when she supposed to be disabled.
