Curiously, in the end credits, only six stories, instead of seven, with the associated cast are displayed. The third story (with Vittorio Gassman) in which Shirley Mac Laine plays the character Linda is omitted.
During production the film was titled "Woman x 7", but was changed somewhere along the line because it sounded too much like the sort of 'cloak and dagger' picture then very much in vogue.
In "The Suicides" vignette, the characters scrawl a French profanity on the wall of their hotel room, yet when they play a long scene in front of a mirror in which the word is reflected, the word doesn't appear backwards as it normally would.
