 The film was one of the last to run into heavy censorship trouble  before the abolition of the Production Code Administration and its  replacement with the voluntary ratings system (G through X) by the  Motion Picture Association of America (MPAA) in 1968. According to  former PCA Director Geoffrey Shurlock (qv), this film was  troublesome due to its depictions of sexual behavior, which the  producers tried to get away with by using silhouettes and shadows.
