Impossible Object, later released as Story of a Love Story, is a 1973 drama film starring Alan Bates and Dominique Sanda.
 It was directed by John Frankenheimer with a screenplay by Nicholas Mosley based on his own novel.
 It was screened at the 1973 Cannes Film Festival, but was not entered into the main competition.
 Mosley wrote the screenplay at the behest of director Joseph Losey, whose film "Accident" was based on an earlier Mosley novel.

 However, Losey had difficulty financing the film and later fell out with Mosley over "The Assassination of Trotsky."
 Frankenheimer, looking to make an independent film, took over the project.
