Love, Harry Burns from When Harry Met Sally (1989)

I came here tonight because when you realize you want to spend the rest of your life with somebody, you want the rest of your life to start as soon as possible.

Love, Billy Crystal as Harry Burns from When Harry Met Sally (1989)

Harry: Well, how does it work?
Sally: I don't know, but not this way.
Harry: How about this way? I love that you get cold when it's 71 degrees out. I love that it takes you an hour and a half to order a sandwich. I love that you get a little crinkle above your nose when you're looking at me like I'm nuts. I love that after I spend the day with you, I can still smell your perfume on my clothes. And I love that you are the last person I want to talk to before I go to sleep at night. And it's not because I'm lonely, and it's not because it's New Year's Eve. I came here tonight because when you realize you want to spend the rest of your life with somebody, you want the rest of your life to start as soon as possible.
Sally: You see? That is just like you, Harry. You say things like that, and you make it impossible for me to hate you, and I hate you, Harry. I really hate you. I hate you.
[They kiss]

Dream, Ray Liotta (voice) as Shoeless Joe Jackson from Field of Dreams (1989)

[Shoeless Joe Jackson has asked Terence Mann to come with them to the cornfield, but Ray is upset because he wasn't invited]
Ray Kinsella: I did it all, I listened to the voices, I did what they told me, and not once did I ask what's in it for me!
Shoeless Joe Jackson: What are you saying, Ray?
Ray Kinsella: I'm saying... what's in it for me?
Shoeless Joe Jackson: Is that why you did this? For you? I think you better stay here, Ray.
...
Ray Kinsella: What are you grinning at, you ghost?
Shoeless Joe: "If you build it -" [gestures toward catcher, who is Ray's father, John Kinsella] "- he will come."
Ray : "Ease his pain. Go the distance." It was him!
Shoeless Joe: No, Ray. It was you.

Field of Dreams is a 1989 film about an Iowa corn farmer who hears a voice telling him: "If you build it, he will come." He interprets this as an instruction to build a baseball diamond in his fields; after he does, Shoeless Joe Jackson and other dead baseball players emerge from the cornfields to play ball.
