Charlie Chan at the Olympics 1937

Charlie Chan at the Olympics (1937) is possibly the most topical Charlie Chan film, as it features actual footage from the 1936 Berlin Olympics. There is also a scene where Charlie crosses the Atlantic in the Hindenburg. This is the 14th film starring Warner Oland as Chan.
Charlie Chan is proud of his oldest son, swimmer Lee (Keye Luke), being chosen to represent the United States at the 1936 Summer Olympics in Berlin. Meanwhile, over the skies of Chan's Honolulu, the "Hopkins plane" is demonstrating an improvement of remote radio control to the US military. The aircraft is hijacked by a concealed stowaway, the device stolen, and the test pilot murdered. When Chan and his astute second son, Charlie Jr. (Layne Tom Jr.), identify the stowaway, he finds only the man's body.
