Trivia

"City Hunter" creator Tsukasa Hôjô had been refusing several offers to adapt his work over the years, because most of the time these works were simple action stories. However, when he met Philippe Lacheau he was impressed with the prepared screenplay: "In Philippe's scenario, there was everything: drama, laughter, things a bit naughty. He had taken into account the totality of the work."

At the very end of the film, a gust of wind lifts a skirt right in front of Nicky, who notices. At that moment, a raven crosses the screen croaking. This is an anime tradition: when somebody does something stupid or foolish, a crow flies past, crying "A-ho! A-ho!" The word "aho" is Japanese for "idiot", and sounds similar to a crow's cawing.

This happened a lot to Nicky Larson in the "City Hunter" anime/manga comic.

Philippe Lacheau is a big fan of City Hunter (1987) (known in France as "Nicky Larson"), having watched it as a child in the 1990s.

Philippe Lacheau spent eight months following a diet and physical training to gain 8 kg of muscles for the role of Nicky Larson.

Vincent Ropion, the French voice actor of Nicky Larson in City Hunter (1987), appears in the film as a journalist.
