Story of a Love Story may well be the least-known of John Frankenheimer's films. Filmed in France, the story concerns highly imaginative author Alan Bates. Though happily married, Bates enters into an affair with Dominique Sanda. Somehow, the whole experience seems unreal. Could Sanda be merely a character in one of Bates' novels, conjured up out of boredom? We won't reveal the answer here; let us just offer our congratulations to Frankenheimer for so stylishly breaking away from his standard "message" mode (as exemplified in The Manchurian Candidate and Seven Days in May). Story of a Love Story was originally released as Impossible Object.
