Continuity mistake: When the curtain gets stuck to Ballantine's pants, at first it's stuck on his side, then in the next shot it's stuck in the middle of his back.

Directed by: George Stevens
Starring: Cary Grant, Joan Fontaine, Sam Jaffe, Victor McLaglen, Douglas Fairbanks Jr.
Factual error: The film is set during the late 1880's in India. The rifles/bayonets carried by all the British soldiers and Thuggee Indians are American 1890's Krag-Jorgensen rifles. Presumably done for ease of supplying American ammunition compared to British .303 ammunition.
Sgt. Thomas 'Tommy' Ballantine: You displease me greatly, and I ignore the both of you.
