Other mistake: Moonlight Graham is hitchhiking; Ray stops to pick him up. The kid talks at the window; Ray says to get in, and he opens the door to get in. No way a kid from the 1920s would know how to open a Volkswagen side sliding door.
Field of Dreams (1989)
1 other mistake - chronological order
Directed by: Phil Alden Robinson
Starring: Kevin Costner, Ray Liotta, Burt Lancaster, James Earl Jones, Amy Madigan
Factual error: Joe Jackson batted left-handed in real life, not right-handed as Ray Liotta portrayed. He also threw right-handed and not left-handed like it shows when Kevin Costner is hitting him fly balls to left field.
Shoeless Joe Jackson: Ty Cobb wanted to play, but none of us could stand the son of a bitch when we were alive, so we told him to stick it.
Trivia: The town in Iowa that the movie was filmed in was Dyersville. The actual house and farm used in the movie are about 2 miles outside of town and are open to the public.
Question: At the end of the movie, the Voice is credited as Himself. Who was really responsible for doing the voice that sent Ray on his journey?
Answer: It was actually his own voice (Kevin Costner) that sent him on the journey. At the end of the movie there's even the part where Ray is recalling the voices he heard and turned to Shoeless Joe Jackson and says, "It was you". At which point Joe Jackson turns around and says, "No Ray. It was you".
