Final film in the "Carry on..." franchise to be shot in black and white.
Barbara Windsor recalled that while filming the scene on the conveyor belt, Charles Hawtrey fainted. She thought it was due to fright, but it turned out that he was drunk. A unit nurse innocently asked if anyone had tried giving him a tip of brandy, to which Kenneth Williams scoffed, "That's the last thing he needs, dear." When she tried to help him, he snapped at her for being "so bloody nice" all the time.
The movie spoofed the Ian Fleming spy and criminal organization acronym, such as SMERSH and SPECTRE from the James Bond films, and UNCLE from the movies and TV series. These acronym spoofs in this picture were BOSH, SNOG, SMUT and STENCH. Their meanings are as follows: BOSH: The British Operational Security Headquarters; SNOG: The Society for the Neutralisation of Germs; SMUT: The Society for the Monopoly of Universal Technology and STENCH: The Society for Total Extinction of Non-Conforming Humans.
First ever James Bond spoof movie.
On her first day of shooting, Barbara Windsor asked friend and co-star Bernard Cribbins if there was anyone she should beware of in the cast. He said, "Oh yeah. Mr Kenny Williams [Kenneth Williams]. He doesn't like anybody new on the show." As it happened, her first scene was with Williams, of who she admitted to being a huge fan. Williams, playing a spy, was wearing an absurd false beard, and when Windsor flubbed her first line, he flared his nostrils and said, "Oh duckie, do get it right." She knew he hated the following mentioned person, so she said to him, ''Ere you, don't you have a go at me with Fenella Fielding's minge hair round yer chops. I won't stand for it." Williams retorted, "Oww! Ain't she lovely?" They became the best of friends thereafter, Williams even accompanying Windsor on her honeymoon ("Well, you've been having it off with this chap for ever, you can hardly call it an 'oneymoon.") after she married Ronnie Knight in 1964.
