Lord Southmere has a ring of Chinese spies chasing him because he has in his possession a secret microfilm, the contents of this microfilm reveals the formula for mysterious Lotus X. After being chased into the Natural History Museum, Southmere hides the film in the bones of a Brontosaurus skeleton. After Southmere's capture, it's up to his old nanny and her hardy band of friends to find the film and keep it from the clutches of the evil Hnup Wan..........and so is the plot for Disney's charmingly silly live action venture. It's not masquerading as anything other than a fun family film, it's got bags of energy, and it boasts a quite delightful premise. Obviously taking its lead from Ealing's brilliant The Ladykillers, One Of Our Dinosaur's Is Missing's strength is that a couple of English old dears are taking on {and defying} a gang of Chinese nasties. Some mirthful gags {both visual and oral} light up the film, including a great sequence as the ladies steal the skeleton and whisk thru London with it on the back of a coal fuelled truck!It's good old harmless fun that doesn't deserve the charge of stereotyping the Chinese, it's 1975 and the cast are having fun, and honestly, so should the family. 7/10

It is not necessary to give a synopsis of one of the worst movies ever made. There are good reviews of this movie available online. I just want to add that as a young teen of about 13 years I went to see this movie with a friend and his father. The movie was double-billed with a Disney classic, Cinderella, which ran first in order to draw an audience. One Of Our Dinosaurs Is Missing began and the audience just kind of slowly filtered out of the theater. Our group was one of the last to leave, and the theater was probably empty before half-an-hour of the movie was through. Don't buy the DVD unless you are a collector. So the next time Disney announced the opening of its "Golden Vault" the video of this stinker better stay right where it is: collecting dust on a shelf.

Helen Hayes and Joan Sims are British Nannies that get involved in espionage trying to find Lotus X. A brilliant comedy, with great performances all round. There are also a lot of familiar faces in small roles. A memorable plot line and a great fight near the end of the film between the Chinese and the Nannies.

I'm not sure why this movie receives as bad reviews as it does. Admittedly, Ustinov's performance is the worst I've seen from him, and nowdays the portrayal of Orientals comes across as out and out racist. But, if you forgive the movie these problems (this was 1976 when sensibilities were different) it's not that bad. Not wonderful, but with a few laughs. And I had little trouble following the plot.
