Psycho II (1983)
Hugh Gillin: Sheriff John Hunt
Sheriff John Hunt : Are you sure neither one of you heard anything between four to five this afternoon?
Norman Bates : No, I was...
Mary : [cutting Norman off] He was with me all afternoon. We were walking in the fields behind the house around that time.
Sheriff John Hunt : Okay. Nice to see you again, Norman.
[the sheriff and his deputy walk out. Mary closes the front door and watches them walk away]
Norman Bates : [to Mary; bewildered] Why did you do THAT?
Mary : Do what?
Norman Bates : Lie to the sheriff. You weren't with me all afternoon!
Mary : I had to do something! He was going to arrest you!
[Norman suddenly holds his head in pain, and slumps down into a nearby armchair]
Mary : Norman, what's wrong?
Norman Bates : It's starting again.
Sheriff John Hunt : [to Norman] There's a girl sitting in my squad car below... too scared to come up here. She claims she saw her boyfriend murdered in your cellar today... by a tall figure wearing a black dress.
