Factual error: After the part where they were at breakfast and discussing the idea of leaving early, you can overhear the radio and the announcer says, "Oh, those Mets! What a team! Finally broke their 22 game losing streak!" The longest losing streak for the New York Mets is currently only 17 games, which was in 1962, a year before the setting of the movie. (01:00:33)
Ken MilotaFactual error: Notice Baby's white Keds shoes with the blue emblem on the back of them. That style of Keds didn't come out until the 80s.
amycamille1975Suggested correction: Keds were released in 1916 and were worn by Marilyn Monroe in the 1952 film "Clash by Night." They did gain major popularity in 1969 after Yoko Ono wore them for her wedding to John Lennon.
Revealing mistake: In the scene when Johnny realises his keys are locked in his car and goes to kick the pole out of the ground there is a light on top of the pole. Where are the wires for the light?
Continuity mistake: When the movie begins and Baby introduces herself, the position of her left hand holding the book changes between shots.

Other mistake: When Johnny breaks his car window, he is getting soaked but Baby is completely dry - her coat never gets wet.
Audio problem: During the "Hula Hana" scene, you can tell the little girl with the ukelele is only mimicking playing. A chord is heard being played in a staccato fashion, but the girl is merely rubbing her thumb against the body, and maybe striking the lowest string, while not fretting any of the strings with her left hand. Playing staccato on open strings would require you to use one of your hands to stop the open strings from ringing.
