Continuity mistake: A gray Ford car starts to chase Hannay; it is initially a Ford Zephyr, then it changes to a Ford Consul and finally reverts to the Zephyr again before it crashes. The car's front grilles are different.
Continuity mistake: When Richard Hannay jumps from the Sheriff's window into a passing truck it is full of bales of hay. The next time we see him in the truck it is full of sheep and the bales of hay have vanished.
