The prison scenes were filmed at
Fort de Bellegarde,
France.
Romani people local to Southern
France stood in for many of the Mexicans. The original director was
Michael Ritchie, but he did not like the idea of the female lead Ann Wagner being played by
Charles Bronson's wife
Jill Ireland. Bronson threatened to leave the project if Ireland was not cast so
Tom Gries came in as director. Producer
Irwin Winkler was not a great admirer of the final film. The film featured a French
Aérospatiale Alouette II turbine helicopter, the type of helicopter used in the 1973
Mountjoy Prison helicopter escape. The actual 1971 Mexico event where Joel David Kaplan broke out of prison featured a
Bell Helicopter.
Actual event The film was loosely based on an actual event that took place in August, 1971 (see
List of helicopter prison escapes). Joel David Kaplan was a
New York businessman and nephew of
molasses tycoon Jacob Merrill Kaplan. The elder Kaplan earned his fortune primarily through operations in
Cuba and the
Dominican Republic. The J.M. Kaplan Fund (named after the elder of the two) was found in a 1964 Congressional investigation to be a conduit for funneling
CIA money to
Latin America, including through the Institute of International Labor Research (IILR) headed by
Norman Thomas, six-time presidential candidate for the
Socialist Party of America. The CIA gave Figures money to publish a political journal,
Combate, and to found a
left-wing school for Latin American opposition leaders. Funds passed from a shell foundation to the Kaplan Fund, next to the IILR, and finally to Figures.
Richard N. Goodwin, Assistant Special Counsel to the President, who had direct contacts with the rebel alliance, argued for intervention against Trujillo. An internal CIA
memorandum states that a 1973
Office of Inspector General investigation into the murder disclosed "quite extensive Agency involvement with the plotters." The CIA described its role in "changing" the government of the Dominican Republic "as a 'success' in that it assisted in moving the Dominican Republic from a totalitarian dictatorship to a Western-style democracy." On August 19, 1971, a helicopter landed in the prison yard. The guards mistakenly thought this was an official visit. In two minutes, Kaplan and Kaplan's cellmate Carlos Antonio Contreras Castro, a
Venezuelan counterfeiter, boarded the craft and were piloted away. No shots were fired. Both men were flown to
Texas and then different planes flew Kaplan to
California and Castro to
Guatemala. Unlike in the film, there was no
rape distraction, no shots were fired, and there was no pursuit by Mexican law enforcement. ==Release==
