[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.
