Square Dance is a movie featuring Winona Ryder and Rob Lowe. This is a rare case where the square dancing in the movie — which is mentioned explicitly three times — is almost accurate. (Usually square dancing is not portrayed very accurately in popular culture.) The grandfather in the movie introduces Ryder’s character Gemma to square dancing moves such as bowing to your partner, dosado, swing, and promenade.
Unfortunately, this movie isn’t about square dancing per se. Square dancing is used as a metaphor for something that the main character is longing for — a simple, predictable life with few complications, where people act the way they are supposed to act.
I’m not sure how long this link will be active, but for now, you can watch the whole movie on YouTube.
If that doesn’t work, you can buy the DVD instead.
