Trivia: Look at the name of the technical adviser in the opening credits - it's "Sun Tan Lo Tion".
Trivia: There was no music played during the filming of the party scene, so the cast members had to improvise their own dance steps as the scene continued. Although music was added to the final film later in production, you will notice that some of the actors are dancing too fast or doing the wrong steps to the music.
Trivia: This was the final "Carry On" movie to feature Charles Hawtrey. Apparently, the actor's addiction to alcohol had worsened since making "Carry On Cowboy" and producer Peter Rogers said this made Hawtrey rather difficult and impossible to deal with, even having to give him black coffee before going in front of the camera. At the end of the filming, the crew's patience had run out and Hawtrey was subsequently fired.
Trivia: Kenneth Williams completely ignored David Kernan during the six weeks of filming.
Trivia: First and only "Carry On" film for Gail Grainger. She replaced Valerie Leon, who was unavailable.
Trivia: Despite receiving prominent billing, Hattie Jacques has only four minutes of screen time.
Trivia: Even though Amelia Bayntun plays Charles Hawtrey's mother, she was five years his junior in real life.
Trivia: In this movie Jimmy Logan goes out of his hotel room and onto a balcony which collapses and he falls into a vat of wet cement. The 'wet cement' you see is actually porridge coloured grey.
