Trivia
Shirley Jones was pregnant during the movie. She wore a special corset to conceal this. Director Morton DaCosta did not want anyone else involved in the movie to be aware of her pregnancy. He was so successful, that it was not until the kissing scene on the bridge that Robert Preston (Harold Hill) found out, when he was shocked to feel Jones' baby kicking him in the stomach.

Revealing: At the end of Winthrop's version of "Gary, Indiana," we see what appears to be a little tap dance done by Winthrop that concludes the song. Upon close observation, however, you can tell that Winthrop does not actually do this dance. He just twirls around and tap noises are added in to make it seem like he is tapping.
Revealing: At a certain point we see the arid, dry Santa Monica Mountains of Los Angeles in the upper left of the picture with a huge high-tension electrical tower at the summit. The film is set in 1912 in Iowa, a green, rainy state which is also completely flat, with no mountains, due to glaciation in the last ice age. Then again, we see the arid, dry Santa Monica Mountains in the upper right.
