Covert Action, badly directed by Romolo Guerrieri, is a predictable, dull espionage drama which concerns an ex-CIA agent (David Janssen) hunted by killers because of a book he has written about his experiences in the agency. While Janssen give a passable performance, the film is poorly plotted and badly directed. Shot on location in Greece, the lovely scenery is the film's only redeeming quality.
