Top Gun

In Top Gun, the scene in which Charlie (Kelly McGillis) tells Maverick (Tom Cruise) that she doesn’t want people to find out about her unprofessional feelings towards him is a well known. Cruise grabs Kelly’s face in the middle of her diatribe and interrupts her with a passionate kiss…which was totally unscripted.

In actuality, the conversation between the two was supposed to have a different conclusion, but Cruise had forgotten his lines. So, instead of having to shoot the scene all over again, he just decided to kiss. The director loved it and the rest, as they say, is history.
