Operation Diplomat (film)

Operation Diplomat is a 1953 British drama film directed by John Guillermin and produced by Ernest G. Roy.

This was one of Guillermin's earliest films. A profile of the director calls it "perhaps the first example of prime Guillermin ... a 70-minute programmer so tautly directed that every image counts, every detail matters, every actor's movement feels perfectly timed – a true gem."

Plot summary
A surgeon operating on an unknown patient discovers that he is involved in the kidnapping of a British diplomat. After his personal secretary is murdered for revealing the patient's identity the police are called in.

Critical assessments
When the film was released The Monthly Film Bulletin called it an "energetic yet improbable figure with too many points left unexplained".

More recently a writer for TV Guide concluded that "this film is hard to swallow, but the non-stop action helps cover up the gaping holes in the plot", and a writer for Filmink asserted that "it's crisply done".
