Goddard's first film in his peculiar choppy style is sort of a takeoff on a cheap American gangster film. In fact, Francois Truffaut has a story credit on the film. However Goddard essentially improvised the film so I doubt the film and Truffaut's story have much in common.
Considering the direction Godard's film career was to take this is a very watchable film. The locations in Paris which are fun to look at were filmed by Raoul Coutard who specialized in on location photography for the French "New Wave."
I enjoyed Breathless a lot because believe me it gets to be a real chore watching Godard films as his career rolls along.
90 minutes, written by Jean-Luc Godard story by Francois Truffaut.
