Dirty Dancing (1987)

Continuity: In the last dance scene, Patrick Swayze jumps down from the stage and starts dancing. He goes down on his knees and when he lifts one knee, it is extremely dusty, however when he stands up his knees are completely clean.

Continuity: When Patrick Swayze and Jennifer Grey are coming back from dancing at another hotel she's changing clothes in the back seat. Patrick Swayze is driving his 1957 Chevy. The car's got an automatic transmission, but they're driving down the road with the shift lever in the PARK position.

Continuity: In the last dance scene of the movie, Patrick Swayze jumps down from the stage and the hair on his forehead which was completely dry is suddenly very wet and plastered to his head.

In Dirty Dancing, the very famous scene where Johnny and Baby are practising their dancing and they are crawling towards each other on the floor, Swayze and Grey were really just messing around and were actually warming up to do the real scene, but the director liked it so much he kept in in the film.

In the scene where Johnny and Baby are practicing dancing, and she keeps laughing when he runs his arm down hers, it was not part of the scene, she was actually laughing and his frustration was genuine. They left it because it was effective. Her falling over in this scene was unplanned too.

The clothes that Baby and Johnny wear contrast. Johnny is always in dark clothing while Baby is always wearing light colours.
