The Chan Calendar
This is a red letter day in Chan history for me because this is the day in 1936 that Twentieth Century-Fox released "Charlie Chan's Secret," my favorite Chan movie!
Twentieth Century-Fox began the production of "Charlie Chan at Ringside" on this date in 1938. As you may know, this is the last Chan movie that Warner Oland worked on but never finished.
The studio managed to recoup losses they suffered by Oland's death by reusing some of the work that had already been filmed. They converted it into a story for Peter Lorre as "Mr. Moto's Gamble," with Keye Luke as Lee Chan and reference to his "Pop" at home in Honolulu.
