In my view, one of the taglines of this movie is aspiration of human nature for 'exploring new horizons' - it doesn't matter where - in performing a stunt with the small plane, in building a novel racing car engine, in establishing a new art direction, in finding something on the bottom of the sea - that may not exist... You may recall how Laetitia looses interest in her dancing partner when he indicates that he doesn't know why all these things are needed.
