Let's begin with a lesson from Gene Kelly, teaching Jerry to dance in Anchors Aweigh (1945):
We move quickly from Kelly's lessons to John Travolta going solo in Saturday Night Fever (1977).
Here is a less sincere scene, from Airplane (1978), with the music from Saturday Night Fever:
Next is a regimental dance from Fort Apache (1948), with Henry Fonda as a stiff dancer.
Nobody is stiff here when Mohammed Rafi sings Jan Pehechan Ho in Gumnamn (1965):
The peasant dance sequence from Sunrise (1927) works better as part of the whole film, but here it is any way. They are new in the big city, not used to its ways, and he does not want to be reminded that he is a peasant. But he surrenders. With George O'Brien and Janet Gaynor.
Here there is no shame, just wordless grace. Cyd Charisse and Fred Astaire in The Band Wagon (1953).
Now more black and white, yet a more recent film, Sally Potter's The Tango Lesson (1997).
Pablo Verón dancing his way through cooking.
It is not unusual for there to be dancing in Patrice Leconte's films. Here Jean Rochefort dances, to a Pakistani song, in The Hairdresser's Husband (1990).
More French dancing, here in Bande à part (1964):
Back to colour and Fred Astaire, this time a scene from Royal Wedding (1951). He is not letting the laws of physics get in the way of a good number. Some feeling.
Finally, the full ballet of the Red Shoes from The Red Shoes (1948). It does not get any better than this.
