Based on a comic by Tsukasa Houjo, City Hunter was made because a Japanese fan mentioned to Jackie Chan that he looks like Ryo Saeba.
Ryo Saeba (Jackie Chan) is asked to bring back Seiko (Kumoko Goto) back to Japan. On their way back, the luxury liner carrying both gets high jacked by gangs. Ryo, Seiko and others battle the gang inside the luxury liner.
The movie is made to appeal to both Hong Kong and Japanese audience, and actor Joey Wong who was popular at the time in Japan appears as Ryo Saeba's girlfriend. Kumiko Goto who was popular in Japan at the time also appears. All star cast of Richard Norton, Leon Lai, and Chingmy Yau also appears to appeal to audiences in both countries. There's a comical scene where characters that looks like the Street Fighter appearing in fight scenes.
This movie is bit different from other Jackie Chan movies, in that body exploitation with many men and women in their swim suit appearing, and overt comedy is part of the story. But the fight scene between Richard Norton and Jackie Chan is pure Jackie Chan movie.
Many people say this is the only Jackie Chan movie that doesn't work, but it is an entertaining movie with some good action spread in between.
