One of Our Dinosaurs Is Missing

Lord Southmere (Derek Nimmo), a Queen's Messenger, wants to get a microfilm of the formula for "Lotus X" out of China and home to England. A group of Chinese spies chases him the whole way, and the trail ends at a dinosaur skeleton in the Natural History Museum. Robert Stevenson, directing for Walt Disney Productions, keeps the 1920s London caper moving at a quick, good-humored clip, with Helen Hayes and Joan Sims in the thick of it.
