Marat/Sade is a play of political theater.
Excerpted from the IMDb database:
As the title implies, the film is entirely a play-within-a-play where most cast members depict both a character from the French Revolution as well as an insane asylum inmate playing that character. While the film (like the later comedy-drama about deSade, "Quills") addresses censorship, it is primarily concerned with a debate between Marat as a representative of revolutionary radical communism, and de Sade as a nihilistic existentialist frustrated with his own and society's violently cruel urges, as well as the futility of revolutionary action to improve mankind.
[Preparer note: The IMDb listing also has a good discussion of performance of the play in high school and college productions.]
The torrent is given here for archive of the play and discussion of its importance.
