Forces occultes / Occult Forces - The mysteries of Freemasonry [1943]

Forces occultes (Occult Forces - subtitled The mysteries of Freemasonry unveiled for the first time on the screen) is a French film of 1943, notable as the last film to be directed by Paul Riche (the pseudonym of Jean Mamy).

Jean Mamy and screenwriter Jean Marquès-Rivière were both journalists, and Mamy himself was part of the Freemasons Order (venerable of the Renan Lodge of the Grand Orient de France). He was part of the order from 1931 and until 1939. He was also part of the inter-war left win in France and sometimes wrote under his pseudonym Paul Riche for left-wing newspapers in the country. During his time with the Order, Mamy learned a lot about the Freemasons, and he used the information to put a genuine and authentic story in the movie.

On France's liberation, its writer Jean Marquès-Rivière, its producer Robert Muzard, and its director Jean Mamy, were purged for "collaborating with Vichy". On 25 November 1945, Muzard was condemned to 3 years in prison and Marquès-Rivière was condemned in his absence (he had gone into self-imposed exile) to death and degradation.

Jean Mamy was executed. Muzard was killed in under suspicious circumstances just few years later. Riviere died in 2000.
