Behind That Curtain is a 1929 American Pre-Code mystery film directed by Irving Cummings, starring Warner Baxter and featuring Boris Karloff. It was the first Charlie Chan film to be made at Fox Studios. It was based on the novel of the same name. Charlie Chan is played by Korean American actor E. L. Park, gets one mention early in the film, then makes a few momentary appearances after 75 minutes. One of the earliest talking movies with Charlie Chan featured in it. The character of Charlie Chan was created by author Earl Derr Biggers, who wrote several mystery novels featuring the character. Biggers based Charlie Chan in part on a Honolulu police officer named Chang Apana. Both the character of Charlie Chan and the real-life Chang Apana worked in Honululu and were accomplished, respected police officers of Chinese descent, but the similarities seem to end there. The first screen appearances of Charlie Chan were in silent serials and the character also had a small role in this 1929 early talkie "Behind That Curtain."
