In a marriage, you're promising to care about everything. The good things, the bad things, the terrible things, the mundane things... all of it, all of the time, every day. You're saying “Your life will not go unnoticed because I will notice it. Your life will not go un-witnessed because I will be your witness”.
Susan Sarandon - Beverly Clark

“- Leslie Crosbie: You won't have to show Bob the letter, will you?
- Howard Joyce: I'll do everything possible to prevent him from seeing it. He'll be an important witness and he should be as firmly convinced of your innocence as he is now.”

Bette Davis - Leslie Crosbie
James Stephenson - Howard Joyce

“- Rachel: When can we leave the city?
- John Book: We're trying to get this done as quickly as possible, then you can go. But Samuel's probably gonna have to come back to testify. I'm sorry.
- Rachel: No, you are not, you are glad. Because now you have a witness.”

Kelly McGillis - Rachel
Harrison Ford - John Book

“- John Book: The man who was killed tonight was a policeman, and it's my job to find out what happened. I want you to tell me everything you saw when you went into the bathroom.
- Samuel: There were two.
- John Book: There were two men?
- Samuel: I only saw one.”
Harrison Ford - John Book
Lukas Haas - Samuel

“- Rachel: You have no right to keep us here.
- John Book: Yes I do. Your son's a material witness to a homicide.
- Rachel: You don't understand. We want nothing to do with your laws.
- John Book: Doesn't surprise me. A lot of people I meet are like that.”
Kelly McGillis - Rachel
