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 <D.McAnally@uq.net.au>

Did You Know?


The film was broadcast on BBC 1 on Saturday November 8th 1986 in place of the canceled light entertainment show "The Late, Late Breakfast Show" and the game show "Every Second Counts". When "The Late, Late Breakfast Show" was canceled by the BBC, due to the death of Michael Lush. 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 500,000 years ago, so Hettie is wrong on multiple counts. See more »

Silly and a tad dated but a fun romp
3 March 2010 | by (United Kingdom) – See all my reviews

Not a perfect film by all means, but it is enjoyable even with its discrepancies. Some of it is very silly, but is still fun. The film is a tad dated and suffers from uneven pacing, but the performances and the sense of fun it has makes up for it. To liven things up, there are a couple of kung fu fights, a silly car chase and a skeleton of a dinosaur that serves the basis of the main. The performances are fun but very over the top, Peter Ustinov's character is so off-the-wall but Ustinov seems to be enjoying himself. Joan Hickson and Helen Hayes are great as two members of a group of nannies that even Mary Poppins fans would love to join perhaps. Derek Nimmo is decent too as the aristocrat who hides a top secret formula in the dinosaur skeleton. A nice soundtrack and good direction help also. Overall, I enjoyed it, I wasn't expecting perfection, I didn't get it, but I liked it. 7/10 Bethany Cox
