Factual error: The movie is supposed to take place over the course of a single summer. In one section of the film, Bobby is reading a story about VP Nixon's recent Presidential nomination, which took place in 1960. Later, he is reading a story of Maury Wills base stealing record, which occurred in 1962.
Continuity mistake: When Bobby comes to say good-bye to Carol her silhouette is seen through a bedsheet. She takes a piece of cloth from the basket, lifts it a little but drops her arms when Bobby comes closer. In the next, close-up shot she is looking at Bobby with her empty hands up in the air. Besides, the clotheslines look way too high for her.
Continuity mistake: When Ted and Bobby leave the pool hall, they run through the rain to a taxi sitting in the street. Despite the fact that the rain is pelting down, the windows of the taxi are open. If you slow down at this point, you can also see that the rain is only falling in front of the camera; it isn't hitting the taxi or the actors.
