Charlie Chan At The Olympics (1937)

When a U.S. military plane is hijacked and its top secret guidance system stolen, detective Charlie Chan (Warner Oland) heads to Germany to attempt to get it back before it falls into enemy hands. By coincidence, his son (Keye Luke) is on the U.S. Olympics swim team. Based on the character created by Earl Derr Biggers and directed by H. Bruce Humberstone (I WAKE UP SCREAMING). The 14th film in the 20th Century Fox Charlie Chan franchise is one of the better entries. The film includes actual footage from the 1936 Berlin Olympics. The mystery is complicated and takes a few twisty turns before it arrives at its satisfying conclusion but the screenplay doesn't allow for any excess fat as director Humberstone pushes it along. The film hints at the trouble in Germany to come and in an amusing bit, Chan flies to Germany on the Hindenburg. With Katherine DeMille (Cecil B.'s daughter), Pauline Moore, Allan Lane, C. Henry Gordon and John Eldredge.
