 This is meant to be an homage to the double features that played in  grindhouses. However, during the initial weeks of release,  exhibitors were reporting that many audience members were leaving  the cinema after the first feature ("Planet Terror by  Robert Rodriguez (I) (qv)), apparently not realizing, or  forgetting, that a second feature was going to be shown. One reason  cited was that many of audience members were too young to remember  when theaters showed double features. The distributor planned some  changes in the campaign while some exhibitors solved the problem by  posting employees by the auditorium doors to remind departing  patrons that the program contains a second feature.
