EDITOR’S NOTE: As the journey through Cannon continues, this week we’re exploring the films of 21st Century Film Corporation, which would be the company that Menahem Golan would take over after Cannon. Formed by Tom Ward and Art Schweitzer in 1971 (or 1976, there are some disputed expert opinions), 21st Century had a great logo and released some wild stuff.

Directed by Romolo Guerrieri (The Sweet Body of Deborah, Ten Thousand Dollars for a Massacre, Detective Belli, The Final Executioner), who wrote this with Nico Ducci, Mino Roli and Vittorio Schiraldi, Covert Action was known in Italy as Sono Stato un Agente C.I.A. It’s based on former C.I.A. agent Philip Agee’s book Inside the Company: CIA Diary. He eventually became disillusioned with the U.S. government’s support for authoritarian governments across Latin America and that they worked for multinational corporations and not for the good of the world. He did work with the producers, but by the end of the movie sued them over his fees and expenses.

Lester Horton (David Janssen) is really Agee, a man who has left the C.I.A. and wants to write about his time with them again, after a first book that put him on their hit list. There’s also a tape that has dirt on the commander of the Athens C.I.A. station (Arthur Kennedy), which is being kept by John Florio (Maurizio Merli), who is married to Horton’s ex-girlfriend Anna (Corinne Cléry).

The C.I.A. commits Horton to a mental ward to get rid of him, giving him shock therapy — this scene is pretty intense — while a Greek inspector (Phillip Leroy) works to discover the truth of what is happening. The spies also want to take out Florio, as his heroin addiction has led to him becoming a liability. To take him out, they send their killer, known as The Silent (Ivan Rassimov) who cooly takes the man out.

This has a great Stelvio Cipriani score, a super dark feel throughout and was Janssen’s last film, released four months after he died by 21st Century. Catherine Bach was the original lead, but was replaced with Cléry.
