Charlie has his youngest helper ever - or at least in any of the 20 Chan films I've seen - as 12-year-old Charlie Jr. joins Number One Son Lee as they both help dad solve a crime.
Lee (Keye Luke) plays a member of the United States Olympic swimming team in this adventure. The repartee between Chan (Warner Oland) and his two sons in here is terrific. Layne Tom Jr. plays Charlie Junior.
The Chan movie is more of an adventure than the normal whodunit as Charlie and the cops travel to the Olympics in Munich, Germany in search of a missing radar-plane "black box." Lee is kidnapped at the games and his dad does everything he can to get his kidnapped son back while not jeopardizing the United States in the process.
This is one of the better Chan films and will be available on DVD in December, 2006, as part of another Charlie Chan DVD package of four movies.
