Like many other racing comedies, 'Those Daring Young Men in their Jaunty Jalopies' suffers from simply having too much going on at once. The film has so many different characters it tries to devote time to, it's easy to forget everything that's going on. It seemed like whenever Tony Curtis appeared on the screen I thought "Oh yeah, forgot he was in this." The film might be considered a multi-car wreck had it not been for Peter Cook and Dudley Moore. Cook plays a British inventor, Moore his trusty sidekick. These two have all the best lines in the movie, and their deadpan delivery is perfect.
