Director Marco Bellocchio replaced Sergio Donati, who had written the story and was to direct, but was forced to drop out due to clashes with actor Gian Maria Volontè.
Gian Maria Volontè happily showed the movie to the heads of PCI (the Italian Communist Party) believing they would have loved it, but they remarked that he "had been fooled" by Lotta Continua (the extra-parliamentary left extremists).
The film incorporates footage of Giangiacomo Feltrinelli's funeral: he was a left-wing publisher mainly known in the English-speaking world for arranging the publication of "Dr Zhivago" in the west.

The character played by Laura Betti was added to the script by Bellocchio himself when he took over. She had been recently dumped by a much younger lover, brother to the composer Hans Werner Henze, and she put much of her real-life scorn, anger and pain into the role.
