Ivan the Terrible, Part II: The Boyars' Plot (1959) on Netflix

The opening scene is in the throne room of the King of Poland, which has a floor resembling a giant chess board. The costumes are rich and ornate, and Polonaises, the music of Poland, play in the background throughout. Prince Andrei Kurbsky (Mikhail Nazvanov), formerly a best friend to Ivan, enters to hand his sword to the King, who receives it, then returns it, symbolizing a new vassal to lord relationship. Some of Kurbsky's formerly Russian lands are thus passed to Polish control. The courtiers in attendance are all smiles and welcoming faces. Many good looking ladies are sizing up Kurbsky. The ladies use their eyes to show interest either in the man or in the words he says.
