Dance, like music, can express every human feeling.
In the movie White Nights (rated PG-13) it expresses political opinions very well. This is the story of a ballet dancer who escaped the Soviet Union where he was not allowed to dance what he wanted. When his plane is forced to land in Siberia, he is made prisoner by a KGB officer who wants to use his return for the official propaganda. The movie did not have as much success as it should. 18 years later, it is a wondefrul classic. You can still buy it for a few bucks on Amazon. It also shows the great Gregory Hines in wonderful performances.
In the following dance, the dancer expresses his longing for artistic freedom. At the time, the Soviets only accepted classic ballet. Observe the modern and daring moves of American dancer Mikhail Baryshnikov, who in real life also fled the Soviet regime. The song is from Vladimir Vysotsky an iconic poet who often criticized the communist regime. The song is about horses running towards the abyss. http://www.YouTube.com/watch?v=Eq9m-bZ6SAQ
