Lord Southmere escapes from China with a microfilm of the formula for the mysterious "Lotus X", and is captured by Chinese spies who have been instructed to retrieve the microfilm from him. Escaping from his captors, Lord Southmere hides the microfilm in the bones of a large dinosaur at the National History Museum. However, he has been followed into the museum by the spies, so Lord Southmere asks Hettie, (his former nanny), to retrieve the microfilm before the spies can find it. He is then promptly recaptured by the head spy, Hnup. Hettie, and her friend Emily (another nanny), devise a plan for a group of nannies to search for the microfilm, but they are unsuccessful in their endeavors. The spies then decide to steal the dinosaur, but are outmaneuvered by Hettie and Emily, who - with a young nanny named Susan - take the dinosaur skeleton on an unforgettable journey around the countryside. When Hettie's two young charges, Lord Castleberry and his younger brother, Truscott, also become ... Written by David McAnally <>

The skeleton prop was apparently used in the scene where C3PO sees the Jawa transporter in Star Wars, which was made at Elstree Studios 2 years later. Presumably the prop was laying around the Studio facility gathering dust... See more »


When the nannies are searching the dinosaur, Hettie observes that if the skeleton fell on them they would be the first people to be killed in a dinosaur in two million years. Dinosaurs actually became extinct about 65 million years ago. Humans emerged only about 200,000 years ago, so Hettie is wrong on multiple counts. See more »

A Carry On for kids!
20 April 2007 | by (United Kingdom) – See all my reviews

What enormous fun! Nannies, toffs with monocles, drunken Scots, loud Yanks, inscrutable Chinese ... every cliché under the sun chases around London in pursuit of a dinosaur skeleton on the back of a lorry.

Such energy, fun, and real "oomph" make this film utterly lovable. it's not subtle, but it's not meant to be. It's a kids' film. I love it as I love the Carry Ons: rip-roaring laughter, unsubtlety, old gags, and corking performances from a range of brilliant character actors.

Look at the cast list! How can anyone not love this film, just from the cast list alone?! Peter Ustinov and Helen Hayes lead the proceedings. Derek Nimmo has a key role. Carry On-ers Joan Sims, Bernard Bresslaw, Amanda Barrie and the supreme Joan Hickson give 100% to their roles.

People seem to be a bit sniffy about this film, but it's so good-natured, warm and funny that it's really rather rude to pick it to pieces for its stereotyping or its clichés. This film is glorious as it is.
