Behind That Curtain is a 1929 American Pre-Code mystery film directed by Irving Cummings and starring Warner Baxter, Lois Moran and Gilbert Emery.

Charlie Chan, who is played by the Chinese American E. L. Park, gets one mention early in the film, then makes a few momentary appearances after 75 minutes.

In London, fortune hunter Eric Durand is romancing the wealthy Sir George Mannering's niece Eve.

He murders the solicitor who is hired by Mannering to investigate him, but is thwarted when explorer and old family friend Colonel John Beetham takes Eve away to British India.

Later she leaves Beetham and goes to San Francisco, where she is followed by the dogged Sir Frederick Bruce of Scotland Yard, who has Durand in his sights.
