Sorry, Wrong Number began as a half-hour radio play in 1943: a woman confined to her bed picks up the telephone, hears two strangers planning a murder, and spends the rest of the night trying to make someone listen.

This quiz covers the play scene by scene, from the crossed line to the last call, along with the operators, police and hospital staff who brush Mrs. Stevenson off. It also takes in the film's added backstory, its stars and director, and how the script came to be written. It suits students revising the play for class, teachers who want a ready multiple choice quiz to print, and fans of old-time radio and classic thrillers.
