Glenda Jackson was fantastic as Charlotte Corday.
In the live version, the Marquis sits in the middle of the actual audience and gives direction to the stage. Toward the end of the play, banners and ribbons came flying out of the stage and over the audience.
The play got me interested in Marat and the French Revolution. He had a skin condition relieved by sitting in an oatmeal bath and he is pictured thus in paintings.
