The Music Man (1962)

Continuity mistake: In the beginning when the Anvil Salesman gets on the train, he sits down, arms to the side, the camera angle changes, and his arms are immediately on his hat adjusting it.

Continuity mistake: As Shirley Jones is singing "In love with Me" at one point, she's sitting down, and is slouching back. The shot changes to the side, and she's sitting up straight, and is much higher against the counter than she was. Her hands have changed position as well, she's no longer holding onto the cup she had in her left hand.

Continuity mistake: After "'Till There Was You," Harold and Marian kiss. A shot of their reflections in the river shows this happening, and then it shows their heads part. When the shot changes to a close up of them they are kissing again.
