The climactic fight scene concludes with an homage to the Batman (1966) TV series, with music similar to that used in the credits and "sound effects" written in the same style - quite in keeping with the comic book theme of this episode.
The cartoon interludes were drawn by Frank Bellamy, an English illustrator most famous for drawing "Dan Dare" for the "Eagle" comic and the daily strip "Garth" for the "Daily Mirror" newspaper.
French title: "Le vengeur volant".
