This poster was placed in the lobby of theaters running WAIT UNTIL DARK: "DURING THE LAST EIGHT MINUTES OF THIS PICTURE THE THEATER WILL BE DARKENED TO THE LEGAL LIMIT TO HEIGHTEN THE TERROR OF THE BREATHTAKING CLIMAX, WHICH TAKES PLACE IN NEARLY TOTAL DARKNESS ON THE SCREEN. IN THOSE SECTIONS WHERE SMOKING IS PERMITTED THOSE PATRONS ARE RESPECTFULLY REQUESTED NOT TO JAR THE EFFECT BY LIGHTHING UP DURING THIS SEQUENCE. AND OF COURSE, NO ONE WILL BE SEATED DURING THIS TIME." Reminding us that not only was smoking allowed in many theaters but that people often bought a ticket and came in whenever they felt like it, particularly in theaters that ran double features, newsreels, etc.
