Trivia

After the filming was completed, the family that owned the farm kept the field and added a small hut with inexpensive souvenirs for sale. As of 2018, visitors were free to come to the field and play baseball as they please between April and November.

"Shoeless" Joe Jackson remarks about Ty Cobb's desire to play at the Field of Dreams (1989), "None of could stand the son of a bitch when he was alive, so we told him to stick it." In real life, the players were very close friends. In Jackson's later life, when he ran a liquor store in South Carolina, Cobb stopped there to buy bourbon. During the sale, Jackson made no sign of recognition to Cobb, until Cobb finally said, "For God's sakes, Joe, don't you remember me?" Jackson somberly replied, "Well, sure, I remember you, Ty. I just didn't think anyone wanted to remember me anymore."

After the movie was completed, test audiences didn't like the original film title "Shoeless" Joe Jackson, because they said it sounded like a movie about a bum or hobo. Universal called director and screenwriter Phil Alden Robinson to tell him that "Shoeless Joe" didn't work, and the studio changed the title of the film to "Field of Dreams." When Robinson heard the news of the change, he called W.P. Kinsella, the author of the book, and told him the "bad" news, but apparently he didn't care, saying that "Shoeless Joe" was the title the publishing company gave the book. Kinsella's original title was "Dream Field."

There was an actual Archibald "Moonlight" Graham. The stories the men shared were actual stories about "Doc" Graham.

Ray Liotta had no baseball experience and batted right-handed, although "Shoeless" Joe Jackson was a lefty. Phil Alden Robinson allowed Liotta to bat with his right, but still put him through several weeks of extensive training with University of Southern California baseball coach and former Brooklyn Dodger Rod Dedeaux in order to be convincing as one of the sport's greatest hitters. Liotta did attempt to play as the real Jackson did, batting lefty and throwing righty, but the reverse of both was so much more natural for him, and he eventually developed a good swing. The scene where he hits a line-drive straight back at Kevin Costner actually happened. Costner's fall on the mound was real, and although it was a surprise, he stayed in character.
