**TURN THE SUBTITLES ON USING THE CAPTION BUTTON AT THE BOTTOM OF THE SCREEN** Robespierre's speech is in Latin, which is not subtitled.
La Révolution française was filmed in 1989 for the 200th anniversary of the French Revolution, charting events from the calling of the Estates-General to the death of Robespierre. Co-produced by France, Germany, Italy, Britain and Canada, it was filmed in English and French. Only the French version is available on DVD - and only now with English subtitles.

For those asking which piece of music is featured in the dance at the beginning of the film, it is Mozart's Minuet No.5 in F Major from "16 Minuets" (K.176).
