The Hong Kong action scenes were shot without official authorization, with a small crew looking out for the Police.
Two Brazilian twin brothers, who were extras on this movie, sold their car to buy a plane ticket and continue the shoot in Hong Kong.
The movie rights to Largo Winch were first sold twenty years prior to this movie to Producer Serge Silberman, whose ambition was to create a franchise that could rival James Bond's. However, he died before being able to work on the project.
Comic Book Writer Jean Van Hamme declared that though Tomer Sisley doesn't look like Largo Winch as drawn by Philippe Francq, he nevertheless resembles the one depicted in the novels, which preceded the comic book series.
