Look Who's Talking (1989)

Factual error: In the beginning sequence where they show the sperm first fertilizing the egg, it is biologically incorrect - only the head part of the sperm enters an egg, everything else stays on the outside and eventually dies off.

Visible crew/equipment: In the scene where John Travolta is racing Kirstie Alley to the hospital, there is one shot where a camera rigging is clearly seen mounted on the hood of Travolta's taxi in the reflection of the storefront windows.

Continuity mistake: When Mikey is talking about his diaper being wet in the crib there is a rattle to his right which appears and disappears throughout the scene.

Trivia: Mollie's father was played by Louis Heckerling, father of the film's director Amy Heckerling.

Mikey: Wait a minute. These things come in different sizes? What are these? Jumbos?

Mollie: I think you should try some of that Nobel Prize winner sperm.
Rona: Get outta here. Nobel Prize winners ejaculating in jars?
Mollie: Well, give it a shot. Don't you want a smart baby?
Rona: That's all I need. A baby telling me what an idiot I am. Like I don't get enough of that at work?

James: Hey, Gerber Face, high five.
