With just a quick Google search, I found an illustrated script for Charlie Chan's Chance (1932) (script and those few stills) online on The Charlie Chan Family website. They have the scripts of a few other lost Fox/Warner Oland Charlie Chans including Charlie Chan's Courage (1934), Charlie Chan's Greatest Case (1933) and Charlie Chan Carries On (1931).
Here are is a review of the film when it was first released: Variety January 1st, 1932
The story of Charlie Chan's Chance was based off Earl Derr Brigger's novel Behind That Curtain which also inspired Behind That Curtain (1929) with E.L. Park and Murder Over New York (1940) with Roland Winters. The novel was published serially in The Saturday Evening Post between March 31st to May 5, of 1928. It's still in print today thanks to the good folks at Academy Chicago Publishers.
It's also interesting to note that this film is the only one in which the author and creator of Charlie Chan, Earl Derr Briggers, was involved. He edited some of the script.
Several Charlie Chans were considered lost at one time but were then discovered so there is still hope for this film. So if you have a moment, please check your attic or basement. Who knows, maybe you have the only surviving copy of Charlie Chan's Case!
