In the midst of the Spanish Civil War, Luis Denard, a former concert pianist and composer, travels to England as a confidential agent of the Republican government. His mission is to buy coal or to deny it to the Fascist rebels. On the ship, he meets bored rich girl Rose Cullen, whose father, Lord Benditch, heads the firm with which Denard will negotiate. On the road to London, he is beaten and robbed by Fascist agents, who do not find the documents he hid in his shoe. At his hotel he enlists the aid of the young maid, Else, who hides his documents in her stocking. When he meets his contacts, Contreras and Mrs. Melandez, he finds they have sold out to the Fascists and want him discredited or killed. They kill the maid, for which Denard takes revenge. Contreras dies of a heart attack as Denard prepares to shoot him, after which Mrs. Melandez takes poison. Unable to buy any coal, Denard tries to persuade the miners to support their fellow workers in Spain, but they put work ahead of principle. His mission a failure, Rose gets an admirer to help him leave the country secretly. Reaching the coast, he learns that Benditch's firm have repudiated their contract with the Fascists, so he has succeeded after all. On the ship, he finds Rose, to whose life he has given meaning.
The screenplay was based on a Graham Greene novel, of the same name. There is evidence of jump cuts, which suggest that editing, to get the running time under two hours, did not help. Though regarded as over long, the film remains true to Greene's original story.
Reception
Critical response
According to "The Big Sleep Comparisons 1945/46", a featurette on the 2000 DVD release of Bacall's later film The Big Sleep, her reviews for Confidential Agent were largely negative, with particular aspersions cast on Bacall's performance, as a "pretty amateur". According to film historian Robert Gitt, host of the featurette, Warner studio head Jack L. Warner was lobbied to order certain scenes in The Big Sleep re-shot in order to rectify performance issues with Bacall identified in Confidential Agent, which he did. In her own autobiography, Bacall said that she begged not to have to do the film, but couldn't break her contract that early, though her career never fully recovered from Confidential Agent.
Graham Greene's response
, generally critical of film adaptations of his works, disagreed with the critics. In 1979, when Philip Purser returned to the question of the casting of Bacall in The Sunday Telegraph, Greene responded and commended the acting of both Bacall and Boyer. He also praised Shumlin as the only American director to make a good film from one of his stories. In a letter to the paper entitled "An Honourable Performance", Greene wrote:
