In the U.S., Pandora’s Box closed not long after it opened. By then, sound had come in and poorly reviewed silent films from abroad were little in demand.Although exhibition records of the time are incomplete, it seems the film was seldom shown in America in the years following its New York debut. One rare and telling screening took place in Newark, New Jersey, at the Little Theater, a second-run house not above showing sensational or exploitive fare.
The film, then synchronized with “thrilling” sound effects and English titles, was described as “The German sensation that actually reveals most of the evils of the world” while offering “Raw reality! A bitter exposé of things you know but never discuss.” Newspaper ads for this 1931 screening warned “Adults Only.”
