This first is perhaps the best scene in the film, though the simplest in terms of production. It comes near the very end. The core of the story is that the King and three members of his court have chastity for three years while they pursue academic studies, but that goes out the window when a Princess visits with her three handmaidens, and hi-jinks ensue.. Anyway, at this point in the tale, the Princess has learned that her father has died, and with war on the verge of breaking out, she has to return home, along with her handmaidens. The men and women each vow to be together in one year from that day. And so, they all have a wistful parting -- which leaves to this absolutely lovely number that fits in beautifully. George and Ira Gershwin's, "They Can't Take That Away from Me."
It helps that the musical arrangement is hauntingly gorgeous.
The scene opens with a long shot, so know that that's Kenneth Branagh, one of the members of the court, singing at the beginning.
