At that time,Jean-Paul Belmondo and Alain Delon who had been top of status as an actor in France. They seemed to enjoy performing light touch gang star movie. Jean Paul and Alain argued who's name should be up or down. I thought it doesn't matter for them. About 28 later they co-worked with "Half A Chance(1998)",they fight fighting over the same woman and became partner...it reminded me of this movie. Also fashion coordinate and soundtrack were great.
