Factual error: When Mainwaring is driving the van and Jones is in the back suffering from malaria, just after Pike shouts out that Jones has changed colour, if you look out the side window you can see a triangular road sign. These did not come into use until the 1960s.
Continuity mistake: When the Walmington platoon stop their van to open the gate to let the sheep out in attempt to hold up the Eastgate platoons van the Eastgate van drives through the gate into the field with Hodges on his motorbike following, but when the camera cuts back to the road the Eastgate van and the motorbike are on the road behind Walmington's van, the Eastgate van and the motorbike are next seen coming out of the field further up the road.
Other mistake: Mainwaring hangs his new cap on a hook on the inside of his office door, the rest of the platoon are having bayonet practice in the hall. Pike is running with the bayonet but misses the dummy and his bayonet goes through the office door and Mainwaring's cap. The bayonet only goes through the cap once, but there are two tears in the cap.eric 64
